Application

1,2-Bis(diphenylphosphino)benzene (DPPB) can be used:
  • As a chelating ligand in the synthesis of luminescent copper(I) halide complexes.
  • In the synthesis of copper-1,2-bis(diphenylphosphino)benzene catalyst which is used for the β-boration of α, β-unsaturated amide.
  • As an alternative to TMEDA for the selective cleavage of sp3 C-X bond in fluoroaromatic coupling reactions catalyzed by iron.
  • As a ligand in the synthesis of alkenylboronates from acetylenic esters.
  • To synthesize copper-diphosphine complexes which are used as homogeneous catalysts for N-formylation of a wide range of amines.

Baeyer-Villiger Oxidation Reaction

The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
