Diazoamides 1a and 1b were prepared from 2-(O-allyl)- and 2-(S-allyl) anilines 2 respectively. Copper(II) catalysed decomposition of 1 resulted in formation of benzofused heterocycles 7 by [2,3]-rearrangement of the intermediate ylide. Rhodium(II) perfluorbutyramide catalysedreaction, however, gave mainly the indoles 8, 9 whereas rhodium(II) acetatecatalysedreaction resulted in a mixture of products
