Protection of Carbonyl Compounds as 1,5-Dihydro-2,4- Benzodioxepines Over HZSM-5 Zeolite, As A Reusable Catalyst

A mild and effecient catalytic method for acetalization of carbonyl compounds as 1,5-dihydro -2,4-benzodioxepines with benzene 1,2-dimethanol using acidic HZSM-5 zeolite as reusable catalyst is described.

Microwave-Assisted Acetalization of Carbonyl Compounds Catalyzed by Reusable Envirocat® Supported Reagents

Envirocat® supported reagents (EPZG, EPZ10, and EPIC) are found to efficiently catalyze the acetalization of carbonyl compounds with 1,2-ethanediol under microwave irradiation under solvent-free conditions. The reagents can be used in repeated experiments to perform the reaction with the same activity.

Reagents and catalysts derived from polybenzimidazole and polystyrene resins with imidazole pendant groups

Abstract Poly(benzimidazole) beads and similar reactive polymers containing benzimidazole groups attached to polystyrene resins have been used to prepare a variety of polymer-supported reagents and catalysts. For example, the polymers can be used to prepare supported palladium 0 catalysts which are effective in the catalytic hydrogenation of nitro compounds or alkenes at room temperature. Poly(benzimidazole) has also been used to prepare a supported regenerable dichromate oxidizing agent. Testing of the reagent under a variety of conditions shows that its effectiveness depends on the percentage of water remaining in the polymer matrix as well as on the temperature used during the preparation of the chromium(VI) complex. However, under certain conditions, poly(benzimidazole) itself is susceptible to oxidative degradation which reduces its usefulness. Sulfonated poly(benzimidazole) is also a useful catalyst in the acetalization of carbonyl compounds. The great thermal stability of poly(benzimidazole) can be used advantageously in other applications such as the gas-phase dehydrohalogenation of trichloroethane to vinylidene chloride.
