Interactions of RuCl3·3H2O with radical cations of aromatic ethers, 1,4-di-tert-butyl-2,5-dimethoxybenzene, 3,5-di-tert-butyl-1,2-dimethoxybenzene and 2-tert-butyl-1,4-dimethoxybenzene, and with aromatic amines, 2,4,6-tri-tert-butylaniline and N,N,N′,N′-tetramethyl-1,4-phenylenediamine, were observed by voltammetry. ESR and UV spectroscopies were used for the study of the the first two ethers. The effect of RuCl3·3H2O was also examined by controlled potential electrolysis.

Rhenium complexes have been shown to catalyze the alkylation of arenes with alkyl halides. When arenes were reacted with an alkyl chloride in the presence of a catalytic amount of rhenium complexes, such as bromopentacarbonylrhenium(I) [ReBr(CO)5], tricarbonylcyclopentadienylrhenium(I) [Re(C5H5)(CO)3] and decacarbonyldirhenium [Re2(CO)10], alkylation of the arenes proceeded under mild conditions to give a mixture of mono- and dialkyl substituted arenes in moderate-to-good yields.
O-Methylation of tert-Alkylpyrocatecholes. Analytical Method for Determination of the Content of Product Mixtures and Way for Preparation of 4-tert-Alkylveratroles
Beger, J.,Meerbote, M.
, p. 119 - 125 (2007/10/02)
The O-methylation of tert-alkylpyrocatecholes with dimethylsulfate leads to a mixture of substituted guaiacoles 6/7, 9/10 and veratroles 5, 6 which are separated by gas/liquid-chromatography for analytical purposes.It is also possible to prepare 4-tert-alkylsubstituted veratroles 5 with good yields in this way.On the other hand, the alkylation of veratrole was only successful with lower tert-alkanols or alkenes.Long-chained tert-alkanols fail in this reaction.The analytical and spectroscopical data of some new 4-tert-alkylveratroles 5a-g are given.
