Crook, James W. published the artcileBehavior of halogen-containing phosphates and phosphonates in urethane foam, COA of Formula: C5H10Cl3O3P, the publication is Journal of Cellular Plastics (1969), 5(2), 119-22, database is CAplus.

(ClCH2CH2CH2O)3P:O (I) was as effective as (ClCH2CH2O)3P:O (II) as a flame-retardant in urethane foam, but had a lower chem. reactivity than II and thus caused less scorch. Foam was prepared from oxypropylated glycerol 100, II 10, (C7H15CO2)2Sn 0.5, triethylenediamine 0.1, H2O 3.5, siloxane-oxyalkylene copolymer 1.0, and tolylene diisocyanate 45.4 parts. Prior to aging, 90% phosphate could be removed by extraction with boiling C6H6. After aging 48 hrs. at 140°, only 1.7% of the original P content could be extracted by boiling C6H6. Extraction with boiling 1:1 aqueous EtOH removed 78% of the P, and the extract was strongly acidic. The strongly acidic products formed during foam making were responsible for scorch. Heating 220 g. II at 150° for 105 hrs. under N gave 3 g. ClCH2CH2Cl (III). When 57.1 g. II and 15.9 g. N,N’-diphenylurea (IV) were heated at 150° under N for 48 hrs., the products isolated were III 17.6, 1,3-diphenyl-2-imidazolidone (m. 211-13°) 3.6, and N,N’-diphenylpiperazine (m. 165.5-7.6°) 5.4 g. The mechanism of the reaction rates of (BrCH2CH2CH2O)3P:O, I, Cl3CP(O)(OEt)2 (Kosolapoff, 1947), BrCH2CH2CH2P(O)(OEt)2 (prepared according to Eberhard, 1965), (ClCH2CHClCH2O)3P:O, and (BrCH2CHBrCH2O)3P:O with IV were compared. I was the least reactive. I showed greater hydrolytic stability than II and was less reactive toward bases. Foams were prepared using Daltocel SF polyester containing I or II and the fire-retardancy was similar according to ASTM D 1692-59T.

Buendia, Julien published the artcileThe Multiple Facets of Iodine(III) Compounds in an Unprecedented Catalytic Auto-amination for Chiral Amine Synthesis, Application In Synthesis of 866-23-9, the publication is Angewandte Chemie, International Edition (2016), 55(26), 7530-7533, database is CAplus and MEDLINE.

Iodine(III) reagents are used in catalytic one-pot reactions, first as both oxidants and substrates, then as cross-coupling partners, to afford chiral polyfunctionalized amines. The strategy relies on an initial catalytic auto C(sp³)-H amination of the iodine(III) oxidant, which delivers an amine-derived iodine(I) product that is subsequently used in palladium-catalyzed cross-couplings to afford a variety of useful building blocks with high yields and excellent stereoselectivities. This study demonstrates the concept of self-amination of the hypervalent iodine reagents, which increases the value of the aryl moiety.

The bridging methylidyne clusters [Co₃(CO)₉{η¹-μ₃-[CP(O)(OR)₂]}] (1, R = Et; 3, R = SiMe₃) with α-phosphoryl substituents were synthesized by reaction of Cl₃CP(O)(OR)₂ with Co₂(CO)₈, followed by protonation. Cluster 3 was also obtained by the reaction of 1 with Me₃SiBr. The structure of 1 was determined by x-ray crystallog. The donor properties of the P:O function toward Lewis acids such as [Cp₂MCl]⁺ (M = Ti, Zr) were used to assemble early-late metal systems.

Aksnes, Gunnar published the artcileIntermolecular hydrogen bond association between phenol and organophosphorus compounds, Synthetic Route of 866-23-9, the publication is Acta Chemica Scandinavica (1960), 1485-94, database is CAplus.

The intermol. H-bond association constants between phenol and 18 organophosphorus compounds were determined at 20° and 50°. The ΔF, ΔH, and ΔS values of the equilibrium reactions vary linearly with the H-bond shift in such a way that an increase in enthalpy is counteracted by a decrease in entropy. The strong influence of the substituents in organophosphorus compounds on the H-bond association constants is discussed in terms of the electronic properties of the P atom and the substituents. The connection between H-bond formation and the proton-transfer reaction is commented on.

The interactions of 2-methyl-6-tert-butylphenol (I) with CHCl₃ and phosphoryl compds, e.g. (Me₂N)₃PO, in cyclohexane, CHCl₃, and CCl₄ solutions were studied by NMR; thermodn. calculations were also reported. H-bonding was proposed; its extent was solvent dependent. The association constant (K) values indicated 1:1 association in all cases. The K values for the association of I with the phosphoryl compounds were less for the CHCl₃ than for the other solutions This change was attributed to the competitive equilibrium between solvent and solute and was discussed and correlated with the proton acceptor or donor property of the solvent.

Cyclodimerization of phenylbutenynes gave bicyclooctatrienes. Cl₂C:CPhCCCl was prepared by 3 methods from Cl₂C:CPhCHO, which was also converted into Cl₂C:CPhCCBr via Cl₂C:CPhCH:CBr₂. Cl₂C:CPhC:CCl was also prepared by a less suitable route, from PhCOCH:CCl₂. Cl₂C:C(C₆Cl₅)CCCl was prepared in 4 steps from Cl₂C:CPhCHO via perchlorination of Cl₂C:CPhCHClCHCl₂ to Cl₂C:C(C₆Cl₅)CHClCHCl₂ with the Ballester reagent. Cyclodimerization of the chlorobutenynes Cl₂C:CRCCR¹ (R = Ph, R¹ = Cl, Br; R = C₆Cl₅, R¹ = Cl) gave bicyclooctatrienes I. Prolonged heating gave II (R = Ph, R¹ = Cl, Br), but Cl₂C:C(C₆Cl₅)CCCl rearranged into II (R = C₆Cl₅, R¹ = Cl) even in the solid state in several days. Hydrolysis of II gave bicyclotrienediones III.

(Z)-(I) and (E)-PhCCl:CClCCCl (II) were prepared from (Z)- and (E)-PhCCl:CClCHO, resp., via PhCCl:CClCH:CCl₂ or PhCCl:CClCH(OH)CHCl₂ and PhCCl:CClCH(OSO₂C₆H₄Me-4)CHCl₂. (Z)-PhCCl:CClCCBr was prepared from (Z)-PhCCl:CClCHO via (Z)-PhCCl:CClCH:CBr₂. In preparing (Z)-ClC(C₆Cl₅):CClCCCl, the Ph group in (Z)-PhCCl:CClCHClCHCl₂ was perchlorinated by Ballester reagent to give intermediate (Z)-ClC(C₆Cl₅):CClCHClCHCl₂. I and II dimerized slowly with partial decomposition in boiling hexane. The primary dimer III was unobtainable; only the pyrolysis product IV (Z = Cl₂) was isolated, 7% from I and 40% yield from II.

Tobe, Yoshito published the artcile[2 + 2] Cycloreversion of [4.3.2]Propella-1,3,11-trienes: An Approach to Cyclo[n]carbons from Propellane-Annelated Dehydro[n]annulenes, Application In Synthesis of 866-23-9, the publication is Journal of the American Chemical Society (2000), 122(8), 1762-1775, database is CAplus.

As a method to generate all-carbon mols. having highly reactive polyyne units from stable precursors, the [2 + 2] cycloreversion of [4.3.2]propella-1,3,11-triene derivatives was developed. To test the efficiency of this method, the reaction was first applied to simple diethynyl- and dibutadiynyl-substituted propellatrienes, which produced upon UV-irradiation linear hexatriyne and decapentayne derivatives, resp. Next, dehydro[12]-, [16]-, [18]-, [20]-, and [24]annulene derivatives annelated by the [4.3.2]propellatriene units were prepared as precursors to the corresponding cyclo[n]carbons, a monocyclic form of carbon clusters. Laser-desorption mass spectra of the dehydroannulenes exhibited, in the neg. mode, peaks due to the corresponding cyclo[n]carbon anions (n = 12, 16, 18, 20, and 24) formed by successive losses of aromatic indane fragments. Solution photolysis of the dehydro[16]annulene and dehydro[18]annulene derivatives formed reactive polyyne intermediates by [2 + 2] cycloreversion which were intercepted by furan to give the corresponding Diels-Alder adducts. The structures and spectroscopic properties of the dehydroannulenes annelated by the [4.3.2]propellatriene units, the precursors to cyclo[n]carbons, and those annelated by the oxanorbornadiene units, the products of the photolysis in furan, are discussed. Safety: mild explosions were reported with the furan trapping products.
