Several ortho- and para-(1-chloro-2,2,2-trifluoroethyl)phenols were prepared from the corresponding alcohols and thionyl chloride in the presence of pyridine. They reacted smoothly with sodium borohydride and Grignard reagents under mild conditions, forming 2,2,2-trifluoroethyl- or 1-trifluoromethylalkylphenols in high yields.
在吡啶存在下,由相应的醇和亚硫酰氯制备了几种邻-和对-(1-氯-2,2,2-三氟乙基)酚。它们在温和条件下与硼氢化钠和格氏试剂顺利反应,以高产率形成 2,2,2-三氟乙基-或 1-三氟甲基烷基苯酚。
