CHEHARDOLI, Gholamabbas et al. [H2-cryptand 222]2+(Br3-)2 as a tribromide-type catalyst for the trimethylsilylation/tetrahydropyranylation of alcohols. S.Afr.j.chem. (Online) [online]. 2011, vol.64, pp. 127-131. ISSN 1996-840X.
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.
