A skeletal rearrangement of dihalogenospiropentanes in the presence of alkyllithium reagents has been systematically studied using a number of gem-dibromospiropentanes. The scope and limitations of this carbenoid rearrangement are outlined and its mechanism is discussed. (c) 2006 Elsevier Ltd. All rights reserved.

A skeletal carbenoid rearrangement of the gem-bromochlorospiropentanes in the presence of methyllithium has been studied. The synthetic and mechanistic aspects of this rearrangement as well as the influence of the halogen atom nature on the reaction pathway are discussed. (C) 2010 Elsevier Ltd. All rights reserved.
