intermediate metal enolate can be trapped as an enol phosphate and further reacted with Grignard reagents in Kumada cross-coupling reactions. By this, a range of silylated cyclobutanone and cyclobutene derivatives becomes accessible.
一系列高度取代的环丁烯酮与锌基亲核试剂进行 1,4-加成反应,对于无位阻受体,无需铜催化剂的帮助。中间体金属烯醇化物可以作为烯醇磷酸盐被捕获,并在 Kumada 交叉偶联反应中进一步与格氏试剂反应。由此,可以获得一系列甲硅烷基化环丁酮和环丁烯衍生物。
