Synthesis of oppositely-polarized difunctional 1,4-diphosphacyclohexanes

Abstract

Trimethylsilylphosphine undergoes radical initiated addition to Et2NP(CHCH2)2 to form the 1,4-diphosphacyclohexane Et2NP(CH2CH2)2PSiMe3 which, along with the MeOH cleavage products Et2NP(CH2CH2)2PH and MeOP(CH2CH2)2PH, constitute a series of novel 1,4-diphosphacyclohexanes containing oppositely-polarized P–substituent bonds.
