, p. 5409 - 5412 (1988)
A novel Wittig variant, termed "siloxy-Wittig rearrangement", has been developed which provides the half-silylated 1,2-diol systems with a high anti-diastereoselectivity.The unusual anti-selectivity is discussed on mechanistic grounds.

Alcohols and phenols are tetrahydropyranylated rapidly in high yields in the presence of catalytic amount of iodine at room temperature. Depyranylation is effected readily by refluxing with iodine in methanol for few hours.
