Ru(II)-Catalyzed rearrangement of 2-aryl-2-(phenylthio)penta-3,4-dienyl 2,2,2-trichloroacetimidates
摘要:
[RuCl(2)(p-cymene)](2) efficiently catalyzes the rearrangement of 2-aryl-2-(phenylthio)penta-3,4-dienyl 2,2,2-trichloroacetimidate to afford (Z)-2,2,2-trichloro-N-(4-aryl-1-(phenylthio)penta-2,4-dien-2-yl) acetamide. Ru carbene is assumed as the reactive intermediate in this rearrangement. (C) 2010 Elsevier B.V. All rights reserved.
