Benzyne and 1-naphthyne (generated from the corresponding halogeno derivatives and the Complex Base NaNH2-ButONa) condense with α,β-unsaturated ketone enolates β-substituted by an aromatic ring and only enolisable in the α'-position, to lead to α-tetralones and/or indanones. The reaction path depends upon the nature of the ketone enolate and, less strongly, on the solvent. The reaction mechanism is
苯炔和1- naphthyne(从相应的卤代衍生物和复基NaNH产生2 -Bu吨与α冷凝ONA),β不饱和酮的烯醇化物通过将芳族环β取代的并且仅在α'-位置烯醇化,至导致α-四氢萘酮和/或茚满酮。反应路径取决于酮烯醇化物的性质,而不太取决于溶剂。讨论了反应机理。这些反应构成许多α-四氢萘酮和茚满酮的新的简单有效的合成方法。
