Thiofluorenone reacts with C-phenyl-N-methylnitrone to give initially a 1,2,5-oxathiazolidine. Spontaneous loss of sulphur monoxide then produces a dipolar species which reacts with a second molecule of thiofluorenone to give 1,2-thiazolidine.

Abstract
Thiofluorenone reacts with C-phenyl-N-methylnitrone to give initially a 1,2,5-oxathiazolidine. Spontaneous loss of sulphur monoxide then produces a dipolar species which reacts with a second molecule of thiofluorenone to give 1,2-thiazolidine.File in questo prodotto:
