title: A carbaboranylmercuric salt catalyzed reaction; highly regioselective cycloisomerization of 1,3-dienes.
abstract: The combination of carbaboranylmercuric chloride (new type of bulky Lewis acid) and silver triflate efficiently catalyzes cycloisomerization of 1,3-dienes at room temperature. The catalytic system gives allyl-substituted azacycles and cycloalkanes in excellent yields with high to complete regioselectivity.
