Novel heteroleptic copper(I) complexes merging the chelating 1,2-bis-diphenyldiphosphine and various L^X type coligands

Three novel heteroleptic mononuclear copper( i ) complexes with a chelating diphosphine 1,2-bis-diphenylphosphinobenzene ligand (dppb) and various monoanionic bidentate LX-type ligand derivatives are described.
