摘要：
The dinuclear mu-alkylidene mu-hydride cation [Pt-2(dppf)(2)(mu-CHCH2Ar)(mu-H)][Br] (2, dppf = Ph2PC5H4FeC5H4PPh2, Ar = p-MeOC6H4) was obtained unexpectedly from reaction of p-methoxybromostyrene (3) with Pt(dppf)Cl-2/NaBH4/norbornene and crystallographically characterized. Solutions of the hydride [Pt(dppf)H](2) (7), prepared by deprotonation of the known cation [Pt-2(dppf)(2)H-3](+) (6) or by treatment of Pt(dppf)Cl-2 with two equiv of LiBEt3H, deposit an insoluble precipitate formulated as [Pt(dppf)H](n) (11), which also gives 2 on treatment with 3.
