Abstract
In the presence of equimolar quantity of BCl3, phenols 1 react with isocyanates and acyl chlorides to give, usually with good-excellent yields, 2-hydroxy-aryl-carboxy-amides 2 and 2-hydroxy-aryl-ketones 3 respectively. A distinctive behaviour of BCl3 in comparison with other Lewis acids is observed.
