A number of alkyl aryl and alkyl heteroaryl ethers have been prepared from (hetero) aryl halides (mainly bromides) and sodium alkoxides, using copper(I)bromide as a catalyst. The influence of the main solvent, the halogen atom, reaction temperature and the presence of oxygen upon the rate and selectivity has been studied. Furthermore the decomposition of the catalyst and the reduction of the aryl halide

A Friedel–Craftsalkylation reaction of thiophenes with glyoxylate imine was developed to give α-aminoesters. In the presence of FeCl3·6H2O as the catalyst, various α-aminoesters were prepared with moderate to high yields (up to 95%) except for some special substrates.

largely determined by steric effects but intramolecular hydrogen bonding in the anti isomer contributes to the variation of the anti → syn rotation barrier. A single crystal X-ray diffraction study of the anti-3,4-diethoxy derivative shows that the orientation of the 3-alkoxy group is very different from that in anti-3-methoxy-2-thienyldi(1-adamantyl)methanol.
