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.

Application

Dichlorotriphenylphosphorane may be used in the synthesis of the following:
  • tertiary benzanilide derivatives
  • N-phosphodipeptides
  • dialkyl phosphorochloridites based on the reaction of trialkyl phosphites
  • naphthalene ring-based calix[3]amide, via reaction with 6-amino-2-naphthoic acid
  • C2v-symmetrical cyclic tetramers of aromatic amides
