Aromatic ethers were conveniently brominated with quaternary ammonium bromide and iodosylbenzene in glacial acetic acid under mild conditions to give the corresponding monobromo-aromatic ethers in nearly quantitative yields.

GaN powder of nanometer scale was prepared by metal organic chemical vapor deposition using diethylgallium azide as precursor. The resulting powder was characterized by XRD and TEM. It has been found that the particle size of the powder obtained is affected by the deposition temperature, and the fine crystals formed in temperature range 500 similar to 650 degrees C were hexagonal.

The phase-transfer catalysts, long-chain quaternary ammonium salts, were rapidly synthesized from fatty alcohols by the reactions with hydrogen halides in the presence of trialkyl amines under microwave irradiation. The catalysts could be widely applied in a variety of quick and new organic reactions, whether by conventional heating or under microwave irradiation. The reaction efficiencies under microwave irradiation were higher than those obtained with conventional heating.

Abstract The anilines could be easily and selectively N-alkylated with alcohols in the presence of a small amount of Raney nickel and with a greatly shortened period under microwave irradiation. A purely non-thermal effect of microwave was observed in the reaction.

The complex of quaternary ammonium halide and hydrogen halide was found to be the very efficient catalyst in the rapid cleavage and esterification of benzyl alkyl ethers with carboxylic acids under microwave irradiation.

The reaction between benzyl ethers and carboxylic acids was catalyzed efficiently by LnBr3(Ln=La,Nd,Sm,Dy,Er), due to its weak Lewis acidity, with microwave irradiation to afford esters.

Several ethers have been synthesized directly from alcohols and alkyl halides without an additional base, in the presence of a quaternary ammonium salt, under microwave irradiation, within a few minutes.

The reactions of carboxylic acids with halides which could not take place by conventional heating are promoted by microwave irradiation in the presence of quaternary ammonium salt as a catalyst, without a base.

Microwave irradiation is very efficient to accelerate the rate of ethoxylation
