摘要: We report a new family of nickel phosphinidene molecular clusters synthesized from the reaction bis(1,5-cyclooctadiene)nickel(0) ([Ni(cod)2 ]) with organocyclophosphine and trialkylphosphine. found that [Ni(cod)2 ] cleaves P-P bonds to generate groups, establishing cyclic molecules as valuable precursors for making charge-neutral passivated by two-electron donor capping ligands. The formation cluster core structure is controlled bulkiness precursor ligand. As demonstration this cluster-forming reaction, we describe three different nuclearity degree ligation: Ni12 (PMe)10 (PEt3 )8 , Ni8 (PMe)6 (PMe3 (PiPr)6 )6 . In addition, show larger cluster, can be used low temperature single-source catalytically active phosphide phase Ni2 P.
