摘要：

Methyleneketenes 2 and imidoylketenes 4, generated from Meldrum's acid derivatives 1 and 2,3-dihydropyrrole-2,3-diones 3, respectively, both rearrange thermally to oxoketenimines 5; the imidoylketene-oxoketenimine rearrangement is reversible and much accelerated by electropositive migrating groups (SMe).
