[H<sub>2</sub>-Cryptand 222]<sup>2+</sup>(Br<sub>3</sub> <sup>–</sup>)<sub>2</sub> as a Tribromide-Type Catalyst for the Trimethylsilylation/Tetrahydropyranylation of Alcohols
Abstract
A stable organic tribromide, [H2-cryptand 222]2+(Br3–)2 was utilized as an active catalyst for the trimethylsilylation/tetrahydropyranylation of alcohols. The method is general for the preparation of OH-protected aliphatic (acyclic and cyclic), aromatic, primary, secondary and tertiary alcohols.
