[reaction: see text] Phosphates from 3-substituted 4,4,4-trifluorobut-2-en-1-ols were found to be effective for construction of CF3-containing quaternary carbon centers by way of Cu(I)-catalyzed Grignard reactions in the presence of catalytic amounts of CuCN and trimethylsilyl chloride (TMSCl) in an anti S(N)2' manner.
[反应:见正文]发现通过Cu(I)催化的格氏试剂,由3个取代的4,4,4-三氟丁-2-烯-1-醇组成的磷酸盐对于构建含CF3的季碳中心有效。在催化量的CuCN和三甲基甲硅烷基氯(TMSCl)的存在下,以反S(N)2'方式进行反应。
