Lewis Acidity of Hydrosilanes: Synthesis of β‐Alkoxy Alcohols via the Triphenylsilane‐Catalyzed Ring‐Opening Reaction of Epoxides

Abstract

Triphenylsilane (Ph3SiH) works as a Lewis‐acidic catalyst for the ring‐opening reaction of di‐ and tri‐substituted epoxides with alcohols, yielding β‐alkoxy alcohols under nearly neutral reaction conditions. This operationally simple protocol allows the facile synthesis of β‐alkoxy alcohols in good‐to‐excellent yield.
