Several mixed palladium(II) complexes bearing 2,3-diarylcyclopropenylidene ligands (aryl = phenyl, mesityl, naphthyl) and triaryl- and trialkylphosphines have been prepared. Single crystal structure details of one of the dimeric chloro-bridged complexes as well as of two monomeric phosphine substituted complexes are presented and compared with appropriate structural features of similar 2,3-diaminocyclopropenylidene- and cycloheptatrienylidene complexes. The new complexes were tested as catalysts in Suzuki–Mijaura coupling reactions with bromo- and chloroarenes and their catalytic activity compared with that of analogous NHC- and cycloheptatrienylidene complexes.
A series of dinuclear chloro-bridged 2,3-diarylcyclopropenylidene palladium(II) complexes (aryl = phenyl, mesityl, naphthyl) were synthesized by oxidative addition of 2,3-diaryl-1,1-dichlorocyclopropenes to palladium black. Beside an investigation of their structural features the deduced mononuclear phosphine substituted complexes A were tested as catalysts in Suzuki–Mijaura coupling reactions of bromo- and chloro arenes.Figure optionsDownload as PowerPoint slide
