Jones, F. William published the artcileFiber-reactive insecticides for wool: organophosphorus esters of nitrogen heterocycles, Formula: C3H3Br2ClO, the publication is Journal of Agricultural and Food Chemistry (1983), 31(2), 190-4, database is CAplus.

O,O-Di-Et phosphorothionate esters and O-Et S-Pr phosphorothiolothionate esters of some pyridazine and 1,2,4-triazole compounds containing a 2-bromoacryloyl ester substituent were synthesized and screened for insecticidal activity against the wool-digesting insects Tineola bisselliella and Anthrenus flavipes. O,O-Diethyl O-[1-(2-hydroxyethyl)-5-methylthio-3-(1,2,4-triazolyl)] phosphorothiolothionate (I) was most active. These compounds were found to be hydrolytically unstable when applied to wool from a boiling acidic dye bath. The extent of this hydrolysis has been determined by the development of a method for estimating organophosphorus esters that are covalently bound to the wool.

Cyclodehydrochlorination of p-RC6H4N(COCHCl2)CH2COC6H4N-O2-p with Me3COK in Me2SO gave the title compounds (I; R = H or EtO2C; X = OH), which reacted with SOCl2 to give I (X = Cl) (II). Solvolysis with MeOH or amination of II with R21NH gave I (X = MeO or NR21, NR21 = ethyleneimino, 1-pyrrolidinyl, or piperidino).

Yang, Tonghao published the artcileCopper-catalyzed radical reactions of 2-azido-N-arylacrylamides with 1-(trifluoromethyl)-1,2-benziodoxole and 1-azidyl-1,2-benziodoxole, Related Products of chlorides-buliding-blocks, the publication is Organic & Biomolecular Chemistry (2016), 14(13), 3376-3384, database is CAplus and MEDLINE.

The reactions of 2-azido-N-arylacrylamides with trifluoromethyl radicals and azidyl radicals were investigated by using Togni’s reagent and Zhdankin’s reagent as the source of these radicals. Under the catalysis of CuI, Togni’s reagent was firstly converted into the trifluoromethyl radical, which then reacted with 2-azido-N-arylacrylamides to afford the corresponding α-(arylaminocarbonyl)iminyl radicals. The cyclization of the iminyl radicals delivered quinoxalin-2(1H)-one products in moderate yields. A similar reaction took place between 2-azido-N-arylacrylamides and the azidyl radical. In the latter cases, the reaction produced 3-azidomethyl and 3-cyano-substituted quinoxalin-2(1H)-ones. This study not only helps to elucidate the factors influencing the cyclization of α-(arylaminocarbonyl)iminyl radicals, but also provided a new approach towards quinoxalin-2-ones.

α-Bromoacrylamidoethyl cyclodextrin (β-CD-2-EDBA) was prepared with β-cyclodextrin, p-toluenesulfonyl chloride and 2,3-dibromo-propionyl chloride. Aroma finishing of silk fabric grafted with 8-CD-2-EDBA was carried out. Optimum grafting process was pH value 9, grafting agent 16% (owf), sodium sulfate 8 g/L, liquor ratio 1:50, and treating at 90°C for 40 min. Grafting ratio of treated silk fabric was high, and fragrance storage and fragrance retention time enhanced significantly. Scanning electron microscope picture proved that B-CD-2-EDBA was successfully grafted onto silk surface. Grafting ratio was tested with phenolphthalein spectral probe method and gravimetric method sep., it was found that the former had higher grafting ratio, while the latter was more accurate.

A novel hemicyanine fluorescent reactive cationic dye was synthesized by the reaction between the free amino group of a hemicyanine fluorescent dye and 2,3-dibromopropionyl chloride. The dye was characterised by proton NMR spectroscopy, high-resolution mass spectrometry, UV-visible absorption spectrometry, and single-photon fluorescence spectrometry. The prepared dye was applied to wool fabrics to give fluorescent orange shades. The color fastness of the dyed wool fabrics was tested. Results show that dyed fabrics using the novel hemicyanine fluorescent reactive cationic dye could be used as fluorescent clothing.

Shi, Lou published the artcileRegio- and Enantioselective Ni-Catalyzed Formal Hydroalkylation, Hydrobenzylation, and Hydropropargylation of Acrylamides to α-Tertiary Amides, Product Details of C3H3Br2ClO, the publication is Angewandte Chemie, International Edition (2021), 60(3), 1599-1604, database is CAplus and MEDLINE.

The development of enantioselective alkyl-alkyl cross-couplings with coinstantaneous formation of a stereogenic center without the use of sensitive organometallic species is attractive yet challenging. Herein, we report the intermol. regio- and enantioselective formal hydrofunctionalizations of acrylamides, forging a stereogenic center α-position to the newly formed C_sp3-C_sp3 bond for the first time. The use of a newly developed chiral ligand enables the electronically-reversed formal hydrofunctionalizations, including hydroalkylation, hydrobenzylation, and hydropropargylation, offering an efficient way to access diverse enantioenriched amides with a tertiary α-stereogenic carbon center which is facile to racemize. This operationally simple protocol allows for the anti-Markovnikov enantioselective hydroalkylation, and unprecedented hydrobenzylation, hydropropargylation under mild conditions with excellent functional group compatibility, delivering a wide range of amides with excellent levels of enantioselectivity.

Treatment of 5-amino-1,3,3-trimethyl-2-methyleneindoline [6872-05-5] with 2,3-dibromopropionyl chloride [18791-02-1] or 5-chloro-2,4,6-trifluoropyrimidine [697-83-6] gives I (R = CH₂BrCHBrCO) [68699-06-9] and I (R = A) [68699-07-0], which are treated with 4-(dimethylamino)benzaldehyde [100-10-7], 4-[(2-chloroethyl)methylamino]benzaldehyde [94-31-5], or 1-methyl-2-phenylindole-3-carboxaldehyde [1757-72-8] to give 6 polymethine dyes. The lightfastness of the dyes on wool was significantly greater than that of the corresponding N-chloroacetyl and parent nonreactive dyes. Attempts to prepare the corresponding 2,4-dichloro-s-triazinyl derivative were unsuccessful.

Asym. catalytic synthesis of 2,3-allenamides from hydrogen-bond-stabilized enynamides in the presence of quinine-based bifunctional squaramide organocatalysts is described. This protocol forms a variety of 2,3-allenamides in high yields and excellent stereoselectivities, in which the elaborated introduction of intramol. H-bonds within the N,N-bidentate amide group constitutes one of the keys to this highly enantioselective transformation. The synthetic practicality of this reaction was demonstrated by the axis-to-center chirality transfer of allenamides to furnish enantiomerically enriched building blocks.
