lithium selenolates, α-selenoalkyllithiums or α-alkoxyalkyllithiums respectively. We took advantage of these reactions as well as of the ones involving the synthesis of atkyllithiums from selenides to propose an original method for geminal di-allylation of the carbonyl group of aldehydes and ketones.
硒缩醛以及混合的(O,Se)缩醛与砷化锂反应,除亚硒酸锂外,还分别生成α-硒代烷基锂或α-烷氧基烷基锂。我们利用这些反应以及涉及从硒化物合成烷基锂的反应,提出了一种用于醛和酮的羰基双双烯丙基化的原始方法。
