Darstellung der ersten Sulfin‐imide (Thion‐S‐imide) mit Perfluormethylgruppen unter Verwendung von Natrium‐hexamethyldisilazanid als schonendes Dehydrohalogenierungsreagenz

Abstract

Preparation of the First Thione S‐Imides with Perfluoromethyl Groups by the Use of Sodium Hexamethyldisilazanide as a Mild Dehydrohalogenation ReagentFrom the reaction of the sulfenyl chloride 1 with the monosilylated amines 2a, b the sulfenamides 3a, b are obtained in good yields. 1,3‐Dehydrohalogenation of 3a, b with sodium hexamethyldisilazanide yields the thione S‐imides 5a, b. Imide 5a reacts with norbornene (6) to produce the isothiazolidine derivative 7. The structures of 5b and 7 are confirmed by X‐ray analyses.
