Silyl Chloride–N-Methylimidazole–Iodine: A Reagent System for the Efficient Silylation of Primary, Secondary, and Tertiary Alcohols
Stawinski and co-workers report that iodine exerts an accelerating effect on the silylation of alcohols in the presence of N-methylimidazole. This silylation is 5–30 times faster than the one that takes place under the standard Corey-Venkateswarlu silylation conditions. Read More
