ABSTRACT:
A known base-induced catalytic ketoform synthesis can now be carried out without sacrificing the directivity of the prior art process, but non-catalytically, that is, in the absence of the phase transfer catalyst heretofore required, provided the ketone/araldehyde is present in large excess from about 2 to about 25 times the calculated molar amount necessary to yield the reaction product. This synthesis obviates the problems of separating and recovering a phase transfer catalyst used in the prior art process.
