乙酰苯肼

Ethyl phenoxyacetate has been synthesised by the reaction of phenol with ethyl chloroacetate under the condition of solid-liquid phase transfer catalysis using PEG-400 as the catalyst.

于固一液相转移催化条件下，以PEG-400为催化剂，通过苯酚与氯乙酸乙酯反应合成了苯氧基乙酸乙酯。与85％的水合肼作用得到相应的酰肼。

This dissertation is mainly focused on the reactivity of methylenecyclopropanes and comprises six parts. 1 The reactions of methylenecyclopropanes with phenylsulfenyl chloride, phenylselenyl chloride and diphenyl diselenide; 2 The coupling reactions of the ring-opening products derivated from methylenecyclopropanes; 3 The palladium-catalyzed ring-enlargement of mono-aryl group substituted methylenecyclopropanes to cyclobutenes. 4 The gold-catalyzed domino ring-opening and ring-closing hydroamination of methylenecyclopropanes with sulfonamides; 5 The Lewis acid-catalyzed reactions of mono-aryl group substituted methylenecyclopropanes with diethyl ketomalonate in the presence of water; 6 The iodobenzene diacetate mediated novel 1,3-dipolar cycloaddition of methylenecyclopropanes, vinylidenecyclopropanes, and methylenecyclobutane with phthalhydrazine.
