A variety of novel triarylmethanes including bis-(dihexyloxyphenyl)arylmethanes and diveratrylmethanes were prepared by the domino Friedel-Crafts alkylation of arenes with aldehydes catalysed by Bi(OTf)3. The reaction of veratrole with aromatic

Simple and efficient methods were developed for sp2-sp3 and sp3-sp3 C-C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported Bronsted acid containing sulfonic groups. The carbocation formed by cleavage of the sp3-sp3 C-C bond of the dione alkylated the aromatic compound.

An efficient method for the synthesis of triarylmethanes and difurylarylmethanes through solventless reactions between aldehydes and arenes in the presence of H3PW12O40 as a reusable catalyst under thermal and microwave irradiation conditions has been developed. H3PW12O40-catalysed one-pot consecutive Friedel-Crafts reactions between veratrole and aldehydes were also applied as a convenient protocol for the preparation of symmetrical 9,10-diaryl-2,3,6,7- tetramethoxyanthracenes.

In the reaction of dimethoxybenzenes with acetylene in the presence of acidic catalysts the corresponding 1,1-diarylethanes are formed as the main products.A trinuclear aromatic compound was also isolated from the products from the reaction of 1,4-dimethoxybenzene with acetylene.Better yields of 1,1-diarylethanes were obtained with H3PO4*BF3 and H2SO4 as catalysts.
