A synthetic and X-ray crystallographic study of the indenyl-phosphine complexes 1,3-(Ph2PX)2(C9H6), (X=O, S) and (η5-C9H5(Ph2PS)2)[Mn(CO)3]: versatile ligands for the preparation of heteropolymetallic complexes
摘要:
The syntheses and X-ray crystal structures of the oxidized indenyl-diphosphines, 1,3-(Ph2P=X),2C9,H-6, where X is O, S, are reported. The sulfur complex is readily deprotonated to form the corresponding 1,3-disubstituted indenide anion, which yields a crystallographically-characterized eta(5)-Mn(CO)(3) complex upon treatment with bromopentacarbonylmanganese. The relevance of these molecules to mixed-metal catalytic systems is discussed. (C) 1998 Elsevier Science S.A. All rights reserved.
