摘要：

Palladacycles of the type Pd(CH2CMe2-o-C6H4)L-2, 2, have been synthesized by treatment of the corresponding chloroalkylcomplexes Pd(CH(2)cMe(2)C(6)H(5))ClL2 (L-2 = (PMe3)(2), 2a, or 1,5-cyclooctadiene (cod), 2b) with suitable bases, or by simple ligand exchange reactions from the cyclooctadiene derivative 2b. The metallacycles 2 react with activated alkynes and with sulfur dioxide, giving rise to different insertion products.
