Nano Copper-Cobalt Ferrite Catalyzed One-Pot Green Combination of β, γ- Unsaturated Ketones by Ultrasonication Method

Abstract

Nano Copper-Cobalt ferrite materials have been used as magnetically separable and reusable heterogeneous catalysts for the synthesis of β, γ - unsaturated ketones over the allylation of acid chlorides with allyl bromides is presented. Ultrasonication method used to the reaction between substituted acid chlorides with allyl halides is carried out in attendance of Nano Copper-Cobalt ferrites at room temperature by using Tetrahydrofuran (THF) as a Solvent. The present method is environmentally benign and gives very good yields. The catalyst is separated from the reaction medium using a strong magnet and reused several intervals without the loss of much catalytic activity. The mechanism of the reaction and characterization of the products are presented
