Filonenko, L. P. published the artcileSilylation of compounds containing trichloromethyl groups, SDS of cas: 866-23-9, the publication is Zhurnal Obshchei Khimii (1987), 57(10), 2320-4, database is CAplus.
Compounds containing the Cl3C group are silylated under mild conditions by the binary system P(NMe2)3/ClSiMe3. Thus, silylation of (Cl3C)2CO gave 50% Cl2C:C(CCl3)OSiMe3.
Zhurnal Obshchei Khimii published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, SDS of cas: 866-23-9.
