A variety of functionalized 5-aryl-3-(trifluoromethyl)phenols were prepared by the first TiCl4-mediated [3+3] cyclocondensation of 1,3-bis(trimethylsilyloxy)-1,3-butadienes with 3-aryl-3-trimethylsilyloxy-1-trifluoromethyl-2-en-1-ones.
通过第一个TiCl 4介导的1,3-双(三甲基甲硅烷氧基)-1,3-丁二烯与3-芳基-3的[3 + 3]环缩合反应,制备了各种官能化的5-芳基-3-(三氟甲基)苯酚。-三甲基甲硅烷氧基-1-三氟甲基-2-烯-1-酮。
