摘要：

The mesoionic thioisomunchnone system was prepared from the rhodium(II) acetate catalyzed cyclization of a diazothioamide and was found to undergo smooth 1,3-dipolar cycloaddition with N-phenylmaleimide. In contrast to this system, the rhodium(II) reaction of an alpha-diazo-beta-oxo ester containing a thiocarbonyl group produced a cyclic thiocarbonyl ylide which extruded sulfur from a transient episulfide intermediate.
