Abstract
Palladium-catalyzed cyclization of benzene-1,2-diol with various propargyli c carbonates led to 2-alkylidene1,4-benzodioxanes in excellent chemical yie lds. Diphosphines such as dppb, dpppe or dpph, and monophosphines are the b est ligands. (C) 1999 Elsevier Science Ltd. All rights reserved.
