Abstract
The regioselective reaction of 2,2 '-dihydroxybiphenyl with terminal alkynes was found to be rapidly catalyzed by InCl(3) and ZrCl(4). The chemoselectivity of catalysts and alkynes for biphenol over water, together with the reaction mechanism are discussed in details.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
