REACTIVE DOUBLE BOND SYSTEMS VIA (3+2) CYCLOREVERSION OF HETEROCYCLES
Schaumann, Ernst
, p. 995 - 1008 (2007/10/02)
After deprotonation, saturated five-membered heterocyclic rings give a facile (3+2) cycloreversion.This approach is employed in syntheses of ketenes, thioaldehydes, thioketones, thioketenes and a thioquinone at low temperature.These highly reactive double-bond systems are usually trapped in situ using (2+2), (2+3), or (2+4) cycloadditions to give various types of heterocycles.
