Synthesis of fluoro-diacetylene monomers: 1,4-Bis(2,4,6-Triaryloxy-difluorophenyl) butadiynes
摘要:
New fluoro-diacetylenes. 1,4-bis(2,4,6-triaryloxy-difluorophenyl)butadiynes, were prepared by nucleophilic substitution reactions on 1,4-bis(pentafluorophenyl)butadiyne, using large excesses of nucleophiles, ArOH, in DMF at room temperature and K2CO3 as base.
