摘要

Extensive studies in ketene chemistry indicate the reaction bias of ketenes with 4-a-electron compounds toward (2+ 2) cycloaddition reactions of these heterocumulenes to yield four- membered-ring compounds.'While the primary synthetic usefulness of the reactions of ketenes remains the formation of four-membered-ring compounds, there are an increasing number of reports in the literature that deal with the (4+ 2) cycloaddition reactions of ...
