The dark orange color produced by the condensation of an excess of lithium compound IV with ketone II was monitored by U.V. and stopped flow spectroscopy.This coloring was ascribed to a lithium compound-ketone complex which evolves into condensation alcohol V.In determining the reaction products we detect the existence of a second inert complex which, when hydrolized, releases the initial ketone.
