An allenic Pauson-Khand-type reaction: a reversal in pi-bond selectivity and the formation of seven-membered rings.

[reaction: see text] Treatment of alkynyl allenes with [Rh(CO)(2)Cl](2) results in a formal [2 + 2 + 1] cycloaddition reaction. This reaction occurs with complete regioselectivity for a variety of substrates affording only 4-alkylidene cyclopentenones in
