Abstract
NEW MATERIAL:A compound of formulaI(R1, R2 are H, alkyl, cycloalkyl, alkenyl, alkynyl and aryl; R1 and R2 incorporate to form cycloalkylidene or cylcloalkenylidene; R3 is lower alkyl, aryl).
EXAMPLE: Diethyl 2-(4-butoxyphenyl)-1,1-defluoro-2-hydroxyethylphosphonate.
USE: Synthetic intermediate of difluoroethene insecticides.
PREPARATION: For example, the reaction between a difluoromethylphosphonic diester of formula II and a trialkylhalosilane of XSiR3 4(R4 is alkyl; X is halogen) gives trialkylsilylphosphonic diester of formula III such as difluoro (trimethylsilyl) methylphosphonic diethyl, which is made to react with a carbonyl compound of R1COR2 such as p-butoxybenzaldehyde to give the compound exemplified.
