Abstract

Acyloins react with urea in the presence of an acid to give 4-imidazolin-2-ones, which can be used as polyamide stabilizers, cotton fabrics crease resistants and synthetic intermediates.'The typical reaction conditions involve refluxing a mixture of an acyloin, urea in solvent with an acid as catalyst for 1-6 hr~.~-~ Recently, application of microwave irradiation in organic chemistry has been developing rapidly.”'We report herein the ...
