Abstract

The tautomerism of the title compounds has been investigated by 1H and 13C n.m.r. and u.v. spectroscopy. The effect of ring size, substituents, and various annellations of the tautomerism have also been studied. The ring size has been found to be decisive from the point of view of tautomerism.
