Preparation of alkyl- and aryl-amino[2H2]methylphosphinic acids
摘要:
Diethyl chloro[H-2(2)]methylphosphonate upon successive treatment with POCl3 and Grignard reagents (RMgX) gave alkyl(chloro[H-2(2)] methyl)pho sphinates. Phenyl(chloro[H-2(2)]methyl)phosphinate was prepared by deuteriolysis of the alpha-silylated alpha-phosphonylated carbanion 11 with D2O. After conversion into trifluoroethyl phosphinic esters, the alkyl- and phenyl-(chloro[H-2(2)]methyl)phosphinates were converted into azides and then reduced and hydrogenated into alkyl- and phenyl-(amino[H-2(2)]lmethyl)phosphinic acids.
