2-Amino-2′-hydroxybenzophenones 3 have been synthesized by acylation of phenols with 2-isocyanatobenzoyl chloride 2 in the presence of aluminium trichloride. The ring-chain tautomerism of the reagent 2 promoted by Lewis acid has been established on the basis of a crystal structure analysis of the 1:1 complex formed by 2 and aluminium trichloride.
在三氯化铝存在下,通过将苯酚与2-异氰酸根合苯甲酰氯2酰化,合成了2-氨基-2'-羟基二苯甲酮3。基于由路易斯酸和三氯化铝形成的1:1配合物的晶体结构分析,已经建立了由路易斯酸促进的试剂2的环链互变异构现象。
