Abstract
Decomposition of alpha-diazosulfoxides using rhodium carboxylate or ca rboxamide catalysts proceeds via a Wolff type rearrangement to form al pha-oxo sulfine intermediates, which can be trapped as cycloadducts wi th dienes. In the absence of a diene trap, dimerisation of the sulfine intermediate is observed. (C), 1998 Elsevier Science Ltd. All rights reserved.
