Ethynyl silyl ketone 1 proved to be a very efficient Michael acceptor in carbocupration and metallocupration reactions. In particular, when using carbocuprates, a smooth entry to polyenals can be obtained, while, when using metallocuprates, silyl- and stannylpropenoyl silanes may be obtained, very powerful intermediates in organic synthesis.
乙炔基甲硅烷基酮1被证明是在碳化和金属定位反应中非常有效的Michael受体。特别是,当使用碳硼酸酯时,可以顺利进入多烯类化合物,而当使用金属碳酸酯时,可以得到甲硅烷基和苯乙烯基丙烯酰基甲硅烷,这是有机合成中非常有效的中间体。
