Abstract

Abstract Synthesis and properties of the new nickel(I) complexes (COD)Ni(TPP)I (3) and (TCP)Nil (5) are reported. Reaction of 3 and 5 with diphenylacetylene (7) yields alkyne complexes (R3P)NiI(PhC2Ph)Ni(R3P)I (R = Ph (8a), and Cy (8b)). In solution, 3 disproportionates to give nickel(O) and (TPP)3Ni3I4 (12)), the structure of which has been determined by X-ray crystallography. Cluster compound 12 is cleaved into monomeric units by addition of ligands such as TPP or CO (TPP = triphenylphosphine, TCP = tricyclohexylphosphine, COD = 1,5-cyclooctadiene).
