What are the applications of Application

Dichlorotriphenylphosphorane is a chemical used in the synthesis of the tertiary benzanilide derivatives

General Description

Dichlorotriphenylphosphorane (Triphenylphosphine dichloride, PPh₃Cl₂) is a phosphorous halide.Stability and reactivity of dichlorotriphenylphosphorane have been studied by solid state ³¹P NMR spectroscopy. It participates in the conversion of carboxylic esters to acid halides and mechanism of this cleavage has been investigated. Modified method has been proposed in which dichlorotriphenylphosphorane participates in the synthesis of tertiary amides.
