摘要：

Attempts to form carbonyl ylides from free carbenes derived from diazirines or diazo compounds lacking electron-withdrawing substituents resulted in azine formation or Wolff rearrangement, respectively. Iodonium ylides proved to be a possible alternative to alpha-diazo compounds for metallocarbenoid generation, similar reactivity being observed for both systems. Studies into the rearrangement chemistry of carbonyl ylides provided a novel cyclic enol-ether synthesis via a 1,4-hydrogen shift process.
