  Cs2CO3-Promoted Vinylation of Phenols with Trichloroethylene: Facile Synthesis of (E)-1,2-Dichloro-1-phenoxyethenes

  摘要：

  An efficient method for the synthesis of (E)-1,2-dichloro- 1-phenoxyethenes 2 has been developed. The reaction of phenol derivatives 1 with trichloroethylene at ambient temperature by means of Cs2CO3-DMSO system furnished the corresponding aryl vinyl ethers 2 in excellent yields. On the other hand, the same reaction of phenol derivatives li, 1k and 1p possessing an electron-withdrawing group at the o- or p-position of the hydroxy group required a harsh reaction conditions to heat at 70 degrees C for the synthesis of the desired products 2i, 2k and 2p.

  A compound according to Formula IA and IB, reversibly convertible under photochromic and electrochromic conditions between a ring-open isomer A and a ring-closed isomer B is provided. For substitutent groups, Z is N, O or S; each R1 is independently selected from the group consisting of H, or halo; each R2 is independently selected from the group consisting of H, halo, a polymer backbone, alkyl or aryl; or, when both R2 together form -CH=CH- and form part of a polymer backbone; each R3 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl; each R4 is aryl; and each R5 is independently selected from the group consisting of H, halo, alkyl, alkoxy, thioalkyl or aryl.
