Ferric chloride–catalyzed deoxygenative chlorination of carbonyl compounds: A comparison of chlorodimethylsilane and dichloromethylsilane system

Deoxygenative chlorination of carbonyl compounds using the HMe2SiCl/FeCl3/EtOAc and HMeSiCl2/FeCl3/EtOAc systems has been systemically investigated. The HMe2SiCl-FeCl3 system showed the advantages of good substrate applicability, mild reaction conditions, simple operation, low cost, and easy availability of raw materials. Also, it provided a simple and efficient synthesis route for carbonyl deoxychlorination via a one-pot method. Using the HMeSiCl2/FeCl3/EtOAc system, the β-methylchalcone derivative could be obtained in good yields in addition to obtaining the chlorinated compound. Finally, two plausible reaction routes were proposed to describe the formation of the chlorinated compound and the β-methylchalcone derivative.

Thionyl chloride-catalyzed preparation of microporous organic polymers through aldol condensation

We demonstrated the synthesis of five kinds of microporous organic polymers based on aldol self-condensation of di- and multiacetyl-containing building blocks catalyzed by thionyl chloride. The α,β-unsaturated ketone (dimerization) and 1,3,5-trisubstitute

New routes for synthesis of branched functionalized benzenoid compounds by using tetrachlorosilane-ethanol reagent

The successive reactions of some cyclic ketones with aryl methyl ketones mediated by tetrachlorosilane-ethanol, provide an attractive and convenient route to branched functionalized benzenoid compounds. Selective unsymmetrical branched triarylbenzenes have synthesized by inducing the reaction of ketones with dypnones in quantitative yields.
