N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of phase-transfer catalysts. The formation of N-, O- and C-products of alkylation was followed by gas chromatography. The N-product was found to be the main product under microwave irradiation. The O-product was obtained in higher yields when an excess of base and benzyl chloride was used.

微波辐射下N-苯基-2-苯基乙酰胺的苯甲酰化

在无溶剂体系中在微波辐射下，在粉末状氢氧化钾存在下，用苄基氯烷基化N-苯基-2-苯基乙酰胺。该反应也在相转移催化剂的存在下进行。气相色谱法随后形成烷基化的N-，O-和C-产物。发现N产物是微波辐射下的主要产物。当使用过量的碱和苄基氯时，以更高的产率获得O产物。
