Substituent Effect on the Formation and Reactivity of Platinum Carbenoids

초록

A propargylic ester containing a propargylic alkoxy group has been observed to preferentially undergo [1,2]-acyl shift over [1,3]-shift. In addition, the complementary and contrasting reactivity of vinyl vs. alkynyl platinum carbenoids has been discovered. Vinyl platinum carbenoids are more prone to undergo [1,2]-H shift over addition to pi-bonds whereas alkynyl platinum carbenoids preferentially add to pi-bonds.
