Organozinc compounds derived from α-bromonitriles are readily prepared in solution in tetrahydrofuran (THF) and exist in the C metallated form. They condense normally with aldehydes and saturated ketones. A number of new β-hydroxy-nitriles are described. The addition of conjugated unsaturated ketones results in the formation of β-hydroxynitriles or ketonitriles, depending on the nature of the initial
衍生自α-溴腈的有机锌化合物很容易在四氢呋喃(THF)中制成溶液,并以C金属化形式存在。它们通常与醛和饱和酮缩合。描述了许多新的β-羟基腈。取决于初始溴腈的性质,共轭不饱和酮的添加导致形成β-羟基腈或酮腈。苯甲醛与锌-α-溴腈的反应的立体化学不受溶剂性质的影响。与丙二酸二乙酯亚烷基的缩合产生预期的1,4-加成产物。
