Twelve heterocyclic aromatic acetals (1a-12a) have been synthesised and their reactions with Lewis acids, viz. boron trifluoride etherate (BTE) and stannic chloride (STC) have been studied.The acetals yield ethers, esters and aldehydes with BTE, but only esters and aldehydes with STC.Interestingly, pyridine-2-aldehyde acetal (12a), yields aldehyde alone, that too in low yield.Probable mechanisms have been suggested for the product formation.

Reactions of twelve heterocyclic aromatic acetals (1a-12a) over solid catalysts such as γ-alumina (AL), aluminium phosphate (AP) and aluminium sulphate (AS) have been studied.The reactions of acetals over AL and AP lead to the corresponding ethers, esters and aldehydes, while over AS the products formed are the corresponding esters and aldehydes.The anomalous behaviour of pyrrole-2-aldehyde acetal (10a) and pyridine-2-aldehyde acetal (12a) over catalysts is of particular interest.Probable mechanisms have been suggested for the reactions.
