corresponding azides by the diazotization method, but the diazo transfer on the conjugate bases with tosyl azide proceeds smoothly and was used in this work as a general method to obtain the azides . The latter thermolyze by two different pathways, depending on the nature of the R4-substituent; i.e. rearrangement to diazoester substituted tetrazoles when R4 = COOR, and decomposition to alkylidenetriazenes
