Thioketene Syntheses, VIII. - Thioketenes by Cycloreversion of 1,3-Dithiolane Derivatives
2-Alkylidene-1,3-dithiolanes are transformed into S,S-dioxides 1 and S-ethyl- 2 or S-arylsulfonium salts 3.After deprotonation at C-5 they form in a cycloreversion thioketenes 5, which can be trapped as thioamides 17, 18.The stabilized thioketenes 5e,i-k afford 1:1 cycloadducts 24a, b, 27a-d with azomethines; in addition, thioketene 5j provides a dimer 28j, which was characterized by an X-ray structural investigation.

DESTABILIZED CARBOCATIONS. NUCLEAR MATNETIC RESONANCE DETECTION AND REACTIVITIES OF ARYL α-THIOFORMAMIDYL CATIONS
A series of α-aryl and diarylthioformamidyl cations were observed by low-temperature nuclear magnetic resonance spectroscopy.These ions undergo efficient cyclization and deprotonation to give benzothiophenes.
