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 pi-bonds whereas alkynyl Pt-carbenoids preferentially add to pi-bonds.
已经观察到包含炔丙烷氧基的炔丙酯优先经历[1,2]-酰基移位而不是[1,3]-移位。此外,还发现了乙烯基与炔基铂类卡宾的互补和对比反应性。乙烯基 Pt-carbenoids 更容易发生 [1,2]-H 转移而不是添加到 pi 键,而炔基 Pt-carbenoids 优先添加到 pi 键。
