One-pot synthesis and the X-ray structures of rhenium(I) diphosphine hydrides, fac-(CO)3(P–P)ReH [P–P=dppp, dppb, and dppfe]
摘要:
The reactions of Re-2(CO)(10) with chelated diphosphines, P-P, where P-P are 1,3-bis(diphenylphosphino)propane (dppp), 1,4-bis(diphenylphosphino)butane (dppb), and 1, 1'-bis(diphenylphosphino)ferrocene (dppfe), in refluxed 1-pentanol or 1-hexanol afford the corresponding hydrides 1-3faC-(CO)(3)(P-P)ReH, (for 1, P-P is dppp, for 2, P P is dppb, and for 3, P-P is dppfe) in high yield. The hydrides 1-3 have been characterized spectroscopically and by X-ray crystal structure determinations. (C) 2004 Elsevier B.V. All rights reserved.
