Transition metal catalysed cross-coupling between benzylic halides and aryl nucleophiles. Synthesis of some toxicologically interesting tetrachlorobenzyltoluenes.
摘要:
The aryl-benzyl cross-coupling in the presence of copper-, nickel-and palladium-catalysts has been investigated with a number of chlorine-and methyl-substituted arylmetal compounds ArM (M= MgBr, ZnCl) and (substituted) benzylic halides ArCH2X. The results have been applied in the selective synthesis of some toxicologically interesting tetrachlorobenzyltoluenes. (C) 1998 Elsevier Science Ltd. All rights reserved.
