Article abstract of DOI:10.1016/0022-328X(90)87195-J

The regioselectivity of the reaction between benzaldehyde and the silylketene acetal prepared from trimethylsilylsenecioate is studied as a function of the catalyst used.CsF leads exclusively to the "branched" product whereas TiCl4 gives the required "lin
