Efficient and mild: The selective monoallylation of 1,2-diols was successfully developed with Pd/Sn bimetallic catalysis in good to excellent yields. This process was carried out with high substrate tolerance under mild conditions (see scheme). The catalyst system achieved the quite high chemoselectivity even in the presence of a 1:1 mixture of the 1,2-diol and mono-ol. Copyright

A typical π-acid tetracyanoethylene and capto-dative olefin dicyanoketene acetals were found to catalyze stereospecific alcoholysis of epoxides at the ambient temperature to 50°C in good yields. Mildness and significant chemoselectivity of the catalysts were demonstrated by intactness of tetrahydropyranyl ether and ethylene acetal groups. A novel regioselectivity associated with anchimeric assistance of the ethereal group on the side chain was observed in the ring opening reaction of the 1,2-disubstituted epoxides.

The catalytic activity of various types of capto-dative ethylenes has been investigated on alcoholysis of epoxides, and dicyanoketene dimethyl acetal (DCKDMA) and dicyanoketene ethylene acetal (DCKEA) are found to be efficient and mild catalysts.
