A transition metal-free domino process has been developed, for the first time, to synthesize (E)-stilbenes, biaryl methanes and biaryl ethers from substituted α,β-unsaturated ketones, benzyl acetones and phenacyl ethers, respectively, in moderate to good yields at room temperature using diethyl aluminium chloride (Et2AlCl) as a Lewis acid.
首次开发了无过渡金属的多米诺法,以中等至良好的程度分别由取代的α,β-不饱和酮,苄基丙酮和苯甲醚合成(E)-对苯二甲酸酯,联芳基甲烷和联芳基醚。在室温下使用二乙基氯化铝(Et 2 AlCl)作为路易斯酸。
