A new procedure for the protection of aldehydes and ketones as thioacetals promoted by catalytic amount of p-toluenesulfonic acid and silica gel has been developed. This procedure offers versatility, short reaction time, excellent yield, and is easy to carry out. A simple filtration followed by removal of solvent in most cases produces pure product.
