A novel class of triarylmethanes (TRAMs) containing one or two biaryl moieties was synthesized efficiently through the Pd(PPh3)4-catalyzed Suzuki-Miyaura cross-coupling reaction of brominated TRAMs with arylboronic acid derivatives. We also demonstrate th

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

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.
Ultrasound-assisted eco-friendly synthesis of triarylmethanes catalyzed by silica sulfuric acid

experimental part, p. 840 - 850 (2012/07/03)
An efficient and eco-friendly synthesis of triarylmethanes by the reaction of arenes with aldehydes in the presence of silica sulfuric acid as a heterogeneous and reusable catalyst under ultrasonic irradiation is reported. The advantages of this protocol are the use of green solvents, inexpensive catalyst, commercially available precursors, reusability of SSA, simple work-up, high yields and short reaction times.

Reaction of electron-rich arenes with acetyl bromide and aldehydes in the presence of silica gel-supported zinc bromide was carried out in benzene to give selectively the corresponding triarylmethanes or 9,10-diarylanthracenes in high yields depending upon the ratio of an arene and an aldehyde. The mild conditions employed are especially noteworthy.
