  Unique ring-methyl deprotonation of η4-1,2-dimethyl-3,4-di(tert-butyl)cyclobutadiene complexes of palladium(II) bearing phosphine ligand

  摘要：

  We report unique ring-methyl deprotonation of an eta(4)-cyclobutadiene complex [PdCl2 (eta(4)-(C4Bu2Me2)-Bu-t)](2) (1). Reaction of 1 with 2 equiv. of triphenylphosphine in the presence of triethylamine afforded an exo-methylene-eta(3)-cyclobutenyl palladium complex [Pd(mu-Cl)(eta(3)-C-4(=CH2)(Bu-t)(2)Me)(PPh3)](2) (3) in quantitative yield. The reaction of complex 1 with 2 equiv. of DPPE gave a cationic complex [Pd(eta(3)-C-4(-CH2)(Bu-t)(2)Me)(DPPE)][Cl] (4a) with the release of HCl. Upon treated with triethylamine and AgOTf, a cationic complex [Pd(eta(3)-C-4(=CH2)(Bu-t)(2)Me)(DPPE)][OTf] (4b) was isolated as yellow microcrystalline solids. The cationic exomethylene- eta(3)-cyclobutentyl structure of 4 was revealed by spectral data together with a crystallographic study for complex 4a. (C) 2003 Elsevier Science B.V.
