A solid complex, conveniently prepared from carbon tetrabromide and sodium triphenylphosphine-m-sulfonate (TPPMS), can be used as an easily recoverable catalyst for the selective acetalization of aldehydes and tetrahydropyranylation of alcohols. The catalyst can be recovered by simple precipitation with ether and can be reused at least 7 times without loss of catalytic activity.
