摘要：

The preparation of several cyclopentadienyliron dicarbonyl eta(1)-2-alkynyl and eta(1)-allenyl complexes is reported. The 3 + 2 cycloaddition reactions of these complexes with sulfur dioxide yielded regioisomeric transition-metal-substituted 1,2-oxathiolen-1-yl oxides (sulfenate esters). One of the eta(1)-allenyl complex SO2 cycloadducts has been characterized by X-ray crystallography. The transition metal can subsequently be cleaved from the sulfenate ester containing complexes under oxidative and nonoxidative reaction conditions to produce a variety of new sulfur-containing heterocycles.
