摘要：

A metallacyclopentene-metallavinylcyclopropane rearrangement and a [4+2] cycloaddition of metalladienes are the novel reactions that take place during the reaction of vinyl-substituted enynes such as 1 (R = H, CH3, E' = CO2CH3) with Pd catalysts such as 2 (R = CH2C3F7). The results support the intermediacy of Pd(IV) complexes 3 on the way to the products 4.
