Holy, A. published the artcilePhosphorylation of nucleosides with trichloromethylphosphonic acid derivatives, HPLC of Formula: 866-23-9, the publication is Tetrahedron Letters (1972), 157-8, database is CAplus.

Ribonucleosides were phosphorylated selectively, to give the 2′-phosphate derivative, with Et trichloromethylphosphonate (I) when the ribonucleoside contained the cis-2′,3′-diol group. Treatment of uridine (over-night) with I in HCONMe2 containing Et3N gave 67% of the corresponding uridine nucleotide. Similarly prepared were the nucleotides of cytidine, adenosine, and 6-azauridine in 23, 45, and 3% yield, resp. Thymidine and 2′,3′-O-isopropylideneuridine did not give the nucleotides as they could not form a cyclic intermediate. -(α-L-Lyxofuranosyl)adenine, in which two cyclic intermediates were conformationally allowed, gave 95% of a nucleotide mixture containing 2- and 3-isomeric phosphates and the 3,5-cyclic phosphate in 23, 37, and 35% yield, resp.

Burger, L. L. published the artcileUranium and plutonium extraction by organophosphorus compounds, Safety of Diethyltrichloromethylphosphonate, the publication is Journal of Physical Chemistry (1958), 590-3, database is CAplus.

Organic phosphates, phosphonates, phosphinates, and phosphine oxides were compared as solvents for U and Pu nitrates. Distribution coefficients for U(VI), Pu(IV), and Pu(VI) indicated a large difference in solvent strength among these groups of compounds The introduction of an electroneg. group greatly reduced the solvent strength. The P-O stretching frequency was correlated with solvent strength for these compounds Some solid complexes of the organophosphorus compounds with UO₂(NO₃)₂ were isolated.

Zhang, Zhenzhen published the artcileCopper-Catalyzed Carbotrifluoromethylation of Unactivated Alkenes Driven by Trifluoromethylation of Alkyl Radicals, Formula: C5H10Cl3O3P, the publication is Chinese Journal of Chemistry (2019), 37(5), 452-456, database is CAplus.

Herein an unprecedented protocol for radical carbotrifluoromethylation of unactivated alkenes is reported. With Cu(OTf)₂ as the catalyst, the reaction of unactivated alkenes, TMSCF₃ and activated alkyl chlorides at room temperature provides the corresponding carbotrifluoromethylation products in satisfactory yields. Directed by trifluoromethylation of alkyl radicals, the method exhibits an excellent regioselectivity that is opposite to those driven by CF₃ radical addition

Dong, Xiao-Yang published the artcileCopper-Catalyzed Asymmetric Coupling of Allenyl Radicals with Terminal Alkynes to Access Tetrasubstituted Allenes, Computed Properties of 866-23-9, the publication is Angewandte Chemie, International Edition (2021), 60(4), 2160-2164, database is CAplus and MEDLINE.

In contrast to the wealth of asym. transformations for generating central chirality from alkyl radicals, the enantiocontrol over the allenyl radicals for forging axial chirality represents an uncharted domain. The challenge arises from the unique elongated linear configuration of the allenyl radicals that necessitates the stereo-differentiation of remote motifs away from the radical reaction site. We herein describe a copper-catalyzed asym. radical 1,4-carboalkynylation of 1,3-enynes via the coupling of allenyl radicals with terminal alkynes, providing diverse synthetically challenging tetrasubstituted chiral allenes. A chiral N,N,P-ligand is crucial for both the reaction initiation and the enantiocontrol over the highly reactive allenyl radicals. The reaction features a broad substrate scope, covering a variety of (hetero)aryl and alkyl alkynes and 1,3-enynes as well as radical precursors with excellent functional group tolerance.

The efficiency of 21 P compounds in epoxy coatings varied in series acids > phosphates .sim. phosphites >> phosphonates. The weight loss, char area, and char volume of epoxy coatings containing tri-Ph phosphite [101-02-0] and tri-Me phosphate [512-56-1] were generally minimized while the intumescence maximized as the concentration of amine catalyst, P compound, and film thickness were increased over a wide range. A combination of a high melting insoluble chlorocarbon and phosphoryltrianilide [5326-10-3] were used to prepare fire retardant pigmented alkyd and chlorinated alkyd paints with excellent water and scrub resistance. The fire retardant properties of epoxy coatings containing (PhO)3P were unchanged after immersion in water at 50.deg. for 24 hr.
