The complex [(dppb)Pt(mu -OH)](2)(BF4)(2) displays high catalytic activity in the thioacetalization of a variety of aldehydes and ketones with mercaptoethanol under very mild conditions. The reaction rate is greatly enhanced by the addition to the reaction mixture of magnesium perchlorate as...
aFor example, they can be prepared by processes including the ion of adducts (e.g. anthracene or cyclopentadiene adducts) of a.,.beta.-unsaturated aldehydes or ketones of the formula CH.dbd.CHR.sup.1 with .alpha.,.beta.-unsaturated nitriles or amides e formula Y--C(R.sup.3).dbd.CHR...
