Synthesis of thiiranes through direct sulfur transfer to cycloalkenes in the thermolysis of a thiophene endoperoxide
摘要:
Thiophene endoperoxide 2, which was prepared by photo-oxygenation of thiophene 1, transfers a sulfur atom to form thiiranes when thermolysed in the presence of cycloalkenes, an unexpectedly efficient process which can be catalysed by the cobalt-tetraphenylporphine complex.
