✦ Synopsis

The acid or base catalysed conversion of a non-conjugated unsaturated carbonyl compound into the conjugated isomer has been frequently used in synthetic procedures. There have been various reports of reactions where the conversion was incomplete or even where no rearrangement appeared to occur (1). As part of a survey of the acid catalysed rearrangement of a series of unsaturated cyclic ketones we have examined the following equilibrium. k--(--)=0 H'_ R-o (I) (II)
