Abstract

Bis (trifluoromethy1) thioketene has been synthesized by cracking its dimer prepared from diethyl malonate, thiophosgene, and sulfur tetrafluoride. It is stable enough to be distilled, handled, and stored without special precautions, yet is highly reactive. Described here are reactions of the thioketene with (a) thiocarbonyl compounds to form dithietanes,(b) olefinic compounds and quadricyclenes to yield thietanes,(e) carbodiimides and azines to give ll3 ...
