Syntheses, characterization, and electrochemistry of compounds containing 1-diphenylphosphino-1′-(di-tert-butylphosphino)ferrocene (dppdtbpf)

The synthesis and characterization of copper(I) and palladium(II) compounds [Cu2(μ-Cl)2(κ2-P,P-dppdtbpf)2] (1), [Cu2(μ-Br)2(κ2-P,P-dppdtbpf)2] (2) [Cu2(μ-I)2(κ2-P,P-dppdtbpf)2] (3), [Cu2(μ-CN)2(κ2-P,P-dppdtbpf)2] (4), [Cu2(μ2-SCN)2(κ2-P,P-dppdtbpf)2] (5), [Cu(κ2-P,P-dppdtbpf) (CH3CN)2]PF6 (6), [Pd(κ2-P,P-dppdtbpf)Cl2] (7) and phosphine disulfide compound dppSdtbpSf (8) are reported. The structures of the compounds 5, 6, 7, and 8 have been determined by single crystal X-ray analysis.
