A mild and general method for the palladium-catalyzed vinylation of aryl bromides has been developed. The use of tetrabutylammonium fluoride (TBAF) as the activator and an inexpensive and nontoxic vinyl donor, 1,3,5,7-tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane (D(4)(V), 1), allows for a general and high-yielding preparation of substituted styrenes.
[反应:见正文]已经开发出一种温和而通用的方法,用于钯催化的芳基溴化物的乙烯基化。使用氟化四丁基铵(TBAF)作为活化剂和廉价且无毒的乙烯基供体1,3,5,7-四甲基-1,3,5,7-四乙烯基环四硅氧烷(D(4)(V),1),允许一般和高产率的取代苯乙烯的制备。
