中文摘要	palladium, iridium, and rhodium complexes of 2-methyleneimidazolines have been synthesized by selective phosphine-assisted activation of the 2-methyl c-h bonds in 2-methylimidazolium compounds. metallacycles of various sizes were obtained in the reaction of phosphine-tethered 2-methylimidazolium compounds and [{m(cod)x}(2)] (m = rh or ir cod = 1,5-cyclooctadiene: x = alkoxyl or cl). representative complexes were characterized by x-ray crystallography. the selectivity for aliphatic c(sp(3))h versus aromatic c(sp(2))h activation could be adjusted by means of the steric bulk of the or ligand, whereby a bulky, or group favors activation of the 2-methyl c(sp(3))-h bond. experimental results confirmed that a methyl c-h activation product (a seven-membered iridacycle) is the kinetic product, while the aryl c-h activation product (a six-membered iridacycle) is the thermodynamic product.
