Recently we reported that the addition of N-chlorosulfonyl isocyanate (CSI) to a vinylcyclopropane proceeded through initial formation of the @-la&am (a lT2s + ll2a cycloadditlon) which could either be reduced and isolated, or allowed to thermally rearrange through carbon-nitrogen bond heterolysis.l It was therefore of considerable interest to note the recent
