Synthesis of 5, 5-disubstituted hydantoins under ultrasound

Published:1995-10-25

Abstract

Sonication of a mixture of industrial grade sodium cyanide aqueous solution and ammonium carbonate in water or alcohol with corresponding aldehyde or ketone results in 5, 5-disubstituted hydantoins. Higher yield of products resulted and shorter reaction time give this route the obvious advantages over conventional method.

Key words: INFRARED SPECTROPHOTOMETRY, ANTISPASMODICS, ULTRASONIC WAVES, SODIUM CYANIDE, HYDANTOINS, AMMONIUM CARBONATE
