Borujeni, Kaveh Parvanak published the artcileSilica-gel-supported aluminum chloride. A stable, efficient, selective, and reusable catalyst for tetrahydropyranylation of alcohols and phenols, Safety of 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, the publication is Synthetic Communications (2006), 36(18), 2705-2710, database is CAplus.
A simple, effective, and highly chemoselective method to form 2-tetrahydropyranyl ethers of alcs. and phenols in the presence of silica-gel-supported aluminum chloride as a heterogeneous Lewis acid catalyst is described. The catalyst can be easily recovered and reused without appreciable change in its efficiency.
