Bridged Ten-?-electron Nine-membered Heterocycles: 9-Phenyl-3,8-methano-1,2-thiazonine and 2,9-Diphenyl-3,8-methanothionin

The title compounds, the first examples of bridged ten-?-electron annulenes, were formed by the reaction of benzocyclopropene with a mesoionic oxathiazolone and dithiolone; 9-phenyl-3,8-methano-1,2-thiazonine is unstable, and its formation was deduced

A methanothiazonine (13) was formed by cycloaddition-extrusion-ring expansion of benzocyclopropene with a mesoionic oxathiazoliumolate (12).The reaction with a dithioliumolate (14) gave the cycloadduct (15), from which a methanothionine (16) and a methano
