摘要

Dialkoxyphosphinothioylthio fatty acid amides of formula where R1 is C1- 4 alkyl, R2 is H or C1- 4 alkyl and R3 and R4 are H, alkyl, aryl or substituted aryl are prepared by reacting a mixture of P2S5, an alcohol (R1OH) and a monohalogen fatty acid amide at 0-125 DEG C. Examples prepare (CH3O)2P(S)SCH2CONHCH3, (C2H5O)2P(S)SCH2CONHCH3 and (CH3O)2P(S)SCH2CONHCH(CH3)2.
