Wang, Xing published the artcileFacile one-pot palladium-catalyzed sequential coupling to diarylmethanes by using aryl methyl ketones as the methylene donors, Category: catalysis-chemistry, the publication is European Journal of Organic Chemistry (2013), 2013(30), 6870-6877, database is CAplus.
A novel palladium-catalyzed coupling reaction of an aryl Me ketone with two mols. of an aryl halide to yield sym. diarylmethanes is described. In the facile one-pot reaction, the aryl Me ketone acts as a formal methylene donor. The exptl. facts, including TLC monitoring, speculated intermediates as the raw materials, anal. of the cesium benzoate coproduct by ex situ IR spectroscopy, and the cross-coupling reactions of two different aryl halides, indicate a mechanism involving a palladium-catalyzed sequential two-step coupling process, in which the presence of a trace amount of H2O is indispensable. The reaction is applicable to a broad spectrum of substrates and delivers the products in good to excellent yields. Access to unsym. diarylmethanes with this method is also explored and various factors are discussed.
