Methyltris(triphenylphosphine)cobalt catalyses the aldol condensation of acetone and ethyl methyl ketone. From acetone mesityl oxide is obtained in ∼70% yield, while from ethyl methyl ketone 3-methyl-2-heptene-5-one and 3-methyl-3-heptene-5-one are formed in equal amounts in a total yield of about 100%. The latter products are known to be those of base-catalysed aldol condensation. The corresponding
甲基三(三苯基膦)钴催化丙酮和乙基甲基酮的醛醇缩合反应。由丙酮异丁烯酸酯以〜70%的产率获得,而由乙基甲基酮以相等的量形成3-甲基-2-庚烯-5-酮和3-甲基-3-庚烯-5-酮,总产率为大约100%。已知后者是碱催化的醛醇缩合的产物。还观察到少量相应的羟醛。反应大多在不存在溶剂的情况下进行。
