摘要

Abstract We describe the unexpected behavior of the arylsulfonylacetylenes, which suffer an “anti-Michael” addition of organolithiums producing their alkynylation under very mild conditions. The broad scope, excellent yields, and simplicity of the experimental procedure are the main features of this methodology. A rational explanation of all these results can be achieved by theoretical calculations, which suggest that the association of the ...
