Natural kaolinitic clay : A mild and efficient catalyst for the tetrahydropyranylation and trimethylsilylation of alcohols

Article abstract of DOI:10.1080/00397919608004777

Natural kaolinitic clay possessing transition metals such as Fe, Ti in its lattice has been found to catalyze efficiently the protection of a variety of alcohols with 2,3-dihydro-4H-pyran (DHP) and hexamethyldisilazane (HMDS) at ambient conditions.
