Thione S-Imides. The Reaction with Carbon-Hetero Atom Double Bond

Article abstract of DOI:10.1246/bcsj.53.1023

9-Fluorenethione S-p-toluenesulfonimide reacted as a 1,3-dipole with imines, oximes, and thiones to form (3+2)cycloadducts, while with symmetrical azines and aldehydes, unsymmetrical azines, N-(p-tolylsulfonyl)imines and fluorenone were obtained as a result of the decomposition of the cycloadducts.
