A convenient synthesis of benzothiophene derivatives
摘要:
(Methylthio)- and 2-bromo-1-(methylthio)benzene are useful synthons to prepare monometallated and bimetallated intermediates which lead to 1-benzothiophenes functionalized in the three and/or two positions. (C) 2002 Elsevier Science Ltd. All rights reserved.

method to access sulfones from aryl halides and sodium alkylsulfinates in the presence of CuCl is reported. Regio- and chemoselectivity for the sulfonylation is observed for polyhalogenated arenes. Mechanistic studies indicate that a copper sulfinate reagent is formed in situ from CuCl and sodium sulfinate based on NMR experiments. Potential reaction intermediates, including excited state aryl halides

Our report describes the facile and scalable preparation of 9H-thioxanthen-9-one 10,10-dioxides via Pd-catalyzed sulfonylative homocoupling of the appropriately substituted benzophenones. This transformation provides a straightforward route to previously unreported sulfone-fluoresceins and -fluorones. Several examples of these red fluorescent dyes have been prepared, characterized, and evaluated as
