Coupling reactions of hindered isonitriles and hindered alkyl thioacids: mechanistic studies
摘要:
The coupling reaction between hindered thioacids and isonitriles is developed and described. The mechanism for the formation of the thiopyruvamide products is explored, and the method is applied to a selection of substrates. (C) 2009 Elsevier Ltd. All rights reserved.

The reaction of monothiocarboxylic acids with dicyclohexylcarbodi-imide affords diacyl sulphides and dicyclohexylthiourea. In some cases the formation of N-acyl-NN′-dicyclohexylthioureas was observed. Diacyl sulphides were also obtained by treatment of O-trimethylsilyl thiocarboxylates with acyl chlorides. The mechanism of diacyl sulphide formation in both reactions is discussed. The reaction of thioacyl
