1.2.3.4- Thiatri azoles

The chemistry of 1,2,3,5-thiatriazoles was covered previously in CHEC(1984) <1984CHEC(6)579> together with data on 1,2,3,4-oxa- and thiatriazoles, and in CHEC-II(1996) <1996CHEC-II(4)733>. Older reviews were cited in the introductions to these texts. Synthetic aspects of 1,2,3,5-thiadiazole derivatives and the isomeric 1,2,3,4-thiatri-azoles were recently reviewed by Begtrup <2004HOU833>. 

Further reaction procedures leading to alkyl cyanatescannot be discussed here. Mentitm has to be made, however, of the sometimes particularly useful thermal degradation of S-alkoxy-1,2,3,4-thiatri-azoles, which are often only prepared in solution. ...
