A three-step, single purification procedure has been developed for the concise synthesis of substituted furans from arylacyl bromides.

A simple method has been developed for synthesis of γ-halo-enones. The approach employs a sequence involving initial indium-mediated allenylation reactions of phenacyl halides with propargyl bromide. This process is followed by acid-promoted rearrangement reactions of the formed homoallenic halohydrins. The new method can be incorporated into routes for the efficient synthesis of various five-membered heterocyclic compounds.

A procedure has been developed for synthesis of 2-alkenyl-2H-indazoles starting from 2-(2-carbonylmethyl)-2H-indazoles, which are prepared by gallium/aluminium- and aluminium-mediated, direct, regioselective alkylation of indazoles with α-bromocarbonyl compounds. The structure of 3-(2H-indazol-2-yl)-2H-chromen-2-one was proven by X-ray crystallography. The styrene- and coumarin-2H-indazoles produced by using the new method were found to have interesting fluorescence properties.

A synthesis of hexahydro-1H-isoindoles (IV) and (VIII) is achieved by a base promoted reaction of homoallenic bromohydrins (II) and (VII).

The new route for the synthesis of furane derivatives is based on indium promoted reaction of arylacyl bromides with propargyl bromides as the key step.

The fabrication and modification of metal zeolite catalysts for the conversion of heavy aromatics were investigated. The catalytic performances for various metal-free 12-MR zeolites were evaluated in terms of conversion, product yields, benzene purity and reaction network analyses using transalkylation of toluene and 1,3,5-trimethylbenzene as the test reaction. The effects of metal content, feed impurity, and steaming treatment on the catalytic performances of Pt/mordenite zeolites prepared by different metal incorporation methods were also examined. A sulfuration technique for fine tuning the catalytic activity of the metal catalyst while sustaining desirable stability and performance was developed and its application for transalkylation of heavy aromatics was illustrated by Pt/ZSM-12 catalyst.
