Abstract
Butyltin trichloride can be used with advantage as a catalyst for the preparation of cyclic acctals from aldehydes and diols, or polyols under mild conditions and with short reaction times. Many 1,3-dioxolanes and-dioxanes can be prepared via acetalization and transacetalization processes. The initial stages of the reaction involve either (i) activation of the aldehyde via formation of RCHO-SnBuCJ, followed by its interaction with the diol, or (ii) formation of the organo-alkoxytin dichloride HO― (CH),, ―O―SnBuCl (n = 2,3), which is followed by the insertion of the aldehyde into the Sn―O bond.
