Investigations on Diazo Compounds and Azides, XXXVII. Diazo Group Transfer onto 2,3‐Diphenylthiirene 1,1‐Dioxide with Diazoalkanes The thiirene 1,1‐dioxide 6 reacts with diazoalkanes ( 2a – d ) not only under diazo group transfer to give 9a or 10b and c but also under loss of sulfur dioxide to form pyrazoles ( 11b, c and 8d ). The bicycles 7 are intermediates of both reactions.
