title: Substituent Effect on the Formation and Their Reactivity of Platinum Carbenoids.
abstract: 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 Pt-carbenoids are more prone to undergo [1,2]-H shift over addition to π-bonds whereas alkynyl Pt-carbenoids preferentially add to π-bonds.
