The preparations of several new cyclopentadienyl iron dicarbonyl η1-2-alkynyl complexes are reported. Their [3+2] cycloaddition reactions with sulfurdioxide and disulfur monoxide yielded transition-metal substituted 1,2-oxathiolene-2-oxides and 1,2-dithiolene-1-oxides, respectively. The transition-metal was cleaved from the oxathiolene-oxide and dithiolene-oxide containing complexes to produce new
