Synthesis and Hydrophosphorylation of pi-Complexes of Dibenzylideneacetone and Cyclic Conjugated Dienones with Homocarbonyl and Carbonylcyclopentadienyl Molybdenum Compounds

摘要

Reactions of dibenzylideneacetone and cyclic cross-conjugated dienones with hexacarbonylmolybdenum(0) and bis[tricarbonyl(cyclopentadienyl)molybdenum(0)] afforded the corresponding complexes with eta(2)-(C=C),eta(2)-(C=O) coordination of the diketone to metal center, regardless of the ligand structure and initial molybdenum compound. The reactivity of the multidentate ligands may change as a result of coordination.
