The dinuclear μ-alkylidene μ-hydride cation [Pt2(dppf)2(μ-CHCH2Ar)(μ-H)][Br] (2, dppf = Ph2PC5H4FeC5H4PPh 2, Ar = p-MeOC6H4) was obtained unexpectedly from reaction of p-methoxybromostyrene (3) with Pt(dppf)Cl2/NABH4/norbornene and crystallographically characterized. Solutions of the hydride [Pt(dppf)H]2 (7), prepared by deprotonation of the known cation [Pt2(dppf)2H3]+ (6) or by treatment of Pt(dppf)Cl2 with two equiv of LiBEt3H, deposit an insoluble precipitate formulated as [Pt(dppf)H]n (11), which also gives 2 on treatment with 3.
Mapping the reaction pathway in palladium-catalyzed cross-coupling reactions
Brown,Cooley
, p. 353 - 359 (2008/10/08)
This paper is concerned with the reaction of palladium complexes of the ligand 1,1′-bis(diphenylphosphino)-ferrocene which have been used to define intermediates in the cross-coupling catalytic cycle. The structure of these intermediates and their interco
