Great property of dendrimers-nickel complex of cyclohexene oxide catalysis.

Dendrimers-nickel complex can well catalyze cyclohexene oxide under solvent-free conditions, the main products were 2 – cyclohexenol, 2 – cyclohexenone, 7 – Miscellaneous oxybis ring [4,1,0] heptane-2 rings – one, and the total selectivity of the three products in the total proportion of the reaction product was above 99%, 2 – cyclohexene selectivity can reach 44 % or more; molecular oxygen which was environmentally friendly was used as oxidant, solvent and reducing agent is not necessary. The catalyst preparation method is simple and it’s insoluble in water and common organic solvents, keeps active in water and air, reusable, meets the requirements of green chemistry development.
