三氟甲基化黄原酸酯的自由基烯丙基化允许制备带有三氟甲基的季碳中心。为了获得满意的加合物产率，必须使用过量的烯丙基三丁基锡试剂。过量的试剂可以通过使用偶氮二甲酸二乙酯（DEAD）方便地去除。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
Radical allylation of trifluoromethylated xanthates allows the preparation of quaternary carbon centers bearing the trifluoromethyl group. An excess of the allyltributyltin reagent must be used in order to achieve satisfactory yields of the adducts. The excess of reagent could be conveniently removed by the use of diethylazodicarboxylate (DEAD). (C) 2001 Elsevier Science Ltd. All rights reserved.
