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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
