Sir: The carbonyl group plays a pivotal role in bringing lati- tude to organic synthesis. The need to relocate this functional group within a molecule occurs with such frequency that in- terest in efficient methods of carbonyl transposition remains high. Various procedures have been developed for effecting site exchange within ~aturatedl-~ and @unsaturated ke- tone ~ , ' ~ ' ~ sometimes in tandem with an alkylation ... Table I.
