  Ring Methyl Activation of 1,2-Dimethyl-3,4-di(tert-butyl)cyclobutadiene Complexes of Palladium Giving exo-Methylene-η³-cyclobutenyl Complexes of Palladium

  摘要：

  We found the first ring methyl activation of an eta(4)-cyclobutadiene complex. Base-promoted ring methyl activation of the cyclobutadiene-palladium(II) complex [PdCl2(eta(4)-C4Me2(Bu-t)(2))](2) (2) in the presence of triethylamine afforded the dinuclear exo-methylene-eta(3)-cyclobutenyl complex [PdCl(eta(3)-C-4(=CH2)Me(Bu-t)(2))](2) (3) in 81% yield. In the case of pyridine as base, a mixture of 3 and [C5H5]NH][PdCl3(eta(4)-C4Me2((BU)-B-t)(2))] (4) was obtained. The complex 4 was alternatively derived from the reaction of 2 with 2 equiv of C5H5N.HCl. The ring methyl activation of 2 in the presence of 2,2'-bipyridine and triethylamine followed by treatment with AgBF4 led to the formation of the cationic complex [Pd(eta(3)-C-4(= CH2)Me(Bu-t)(2))(bipy)]]BF4 (6) in 83% yield. The mononuclear exo-methylene-eta(3)-cyclobutenyl structure of 6 was confirmed by spectral data and a crystallographic study.
