Simple reactions involving loss of ROH

Alongside ester condensations ranks a series of simple condensations that involve formation of a new carbon-carbon bond with loss of an alcohol but that can be applied only in isolated cases. One such is the condensation of acetals with aromatic compounds with loss of alcohol, as when ethyl diethoxy-acetate and nerolin (methyl 1-naphthyl ether) in glacial acetic plus sulfuric
