(Chemical Equation Presented) A mild and efficient method for the preparation of O,O-mixed, O,S- and N,O-acetals from symmetrical O,O-acetals has been developed. Thus, the treatment of symmetrical O,O-acetals with TESOTf and 2,4,6-collidine formed weakly

A process for the preparation of enol ethers of the general formula I STR1 in which R1,R2,R3,R4,R5 denote C1 -C20 alkyl, C1 -C20 alkenyl, or C7 -C20 phenylalkyl, R2,R3,R4 denote hydrogen, aryl, cyano, --COOR5, C1 -C12 alkyl monosubstituted to trisubstituted or interrupted by --COOR5, --C=O, cyano, or C1 -C12 alkoxy, C1 -C12 alkyl monosubstituted to trisubstituted by --COOR5, --C=O, cyano, or C1 -C12 alkyl, or C7 -C20 phenylalkyl and R2 and R4 or R3 and R4 together form a C3 -C10 alkylene chain or a C2 -C20 alkylidene chain, from acetals or ketals.
