SOME NEW ASPECTS OF TRANSKETALIZATIONS AND ACETONATIONS OF 1,2,n-TRIOLS (n = 3, 4 ) USING 2,2-DIMETHOXYPROPANE AND 2-METHOXYPROPENE IN THE PRESENCE OF BUTYLTIN CHLORIDES: BuSnCl3, Bu2SnCl2, Bu3SnCl, (Bu2SnCl)2O AND BuSn(OH)2Cl

Transketalizations and acetonations of 2,2-dimethoxypropane and 2-methoxypropene, respectively, using 1,2,3-propane and 1,2,4-butanetriol have been carried out, at room temperature, under the mediation of the following butyltin chlorides: BuSnCl3, Bu2SnCl2, Bu3SnCl, (Bu2SnCl)2O and BuSn(OH)2Cl.The main products are represented by 1,3-dioxolane derivatives when the four mediators are employed.When BuSn(OH)2Cl is employed, particularly in the case of acetonation, a mixture of dioxolane derivatives together with two acetone ketals containing 1,2-O-isopropylidenetriol residues is obtained.
