  Suzuki–Miyaura reactions of the bis(triflates) of 1,3- and 1,4-dihydroxythioxanthone. Electronic and steric effects on the site-selectivity

  摘要：

  The palladium(0)-catalyzed Suzuki cross-coupling reactions of the bis(triflates) of 1,3- and 1,4dihydroxythioxanthone afforded various aryl-substituted thioxanthones. While the Suzuki reactions of the bis(triflate) derived from 1,3-dihydroxythioxanthone proceeded by site-selective attack in favor of position 3, the reactions of the bis(triflate) of 1,4-dihydroxythioxanthone proceeded in favor of position 1. The site-selectivity is controlled by steric and electronic parameters. (C) 2011 Elsevier Ltd. All rights

  The palladium(0)-catalyzed Suzuki cross-coupling reaction of the bis(triflate) of 1,3-dihydroxythioxanthone afforded various aryl-substituted thioxanthones. The reactions proceeded with very good site-selectivity in favour of position 3, due to steric reasons. (C) 2011 Elsevier Ltd. All rights reserved.
