Abstract
Trimethylsilyldiazomethane is compared with ethyl diazoacetate for the rhod ium, copper, and cobalt catalyzed formation and [2,3] rearrangement of ally lsulfonium ylides. At room temperature, the reaction can be carried out usi ng the allyl sulfide as the limiting reagent by slow addition of 3 equivale nts of the diazo compound. Slightly better yields were obtained with trimet hylsilyldiazomethane than with ethyl diazoacetate. (C) 1999 Elsevier Scienc e Ltd. All rights reserved.
