A Novel and Selective Method for Hydrolysis of Acetals and Ketals.-Various cyclic and acyclic acetals/ketals are hydrolyzed by a catalytic amount of CBr 4 under different energy sources, thermal and ultrasound. Dioxolans and dimethyl acetals (I) and (III) are not hydrolyzed under ultrasound, whereas the diethyl acetal gives good yield of ketone (IV).

A Facile and Highly Efficient Sonochemical Synthesis of Organostannane via Barbier Reaction.-Using this method aryl-, alkyl-, allyl-, and vinylstannanes can be prepared efficiently. Interestingly, the 1,1-dibromide (VIII) only yields the monosubstituted derivative (IX), while other dibromides like (VI) lead to disubstituted compounds.
