Very fast, ligand-free and aerobic protocol for the synthesis of 4-aryl-substituted triphenylamine derivatives

A fast, convenient and ligand-free protocol for the synthesis of a series of 4-aryl-substituted triphenylamine derivatives by a palladium-catalysed aerobic Suzuki reaction of aryl halides with [4-(diphenylamino)phenyl]boronic acid in aqueousiPrOH is described. Importantly, both aryl bromides and heteroaryl halides afforded good to excellent yields under mild conditions. A facile, efficient and general ligand-free Suzuki reaction in aqueous iPrOH is described. Under the optimized conditions, both aryl bromides and heteroaryl halidesreacted rapidly with [4-(diphenylamino)phenyl]boronic acid, providing a series of 4-aryl-substituted triphenylamine derivatives in good to excellent yields.

Accelerating charge transfer in a triphenylamine-subphthalocyanine donor-acceptor system

We have designed, synthesized and probed a dodecafluoro-subphthalocyaninato boron(iii) unit, which bears a triphenylamine moiety in its axial position, as a novel electron donor-acceptor system. The Royal Society of Chemistry.

Photochromism of arylchromenes: Remarkable modification of absorption properties and lifetimes of o-quinonoid intermediates

(Chemical Equation Presented) A significant π-conjugation in 6- and 7-arylchromenes manifests dramatically in the absorption properties of their photogenerated o-quinonoid intermediates. This in conjunction with facile synthesis via Suzuki coupling may render a myriad of photochromic arylchromenes with wide-ranging spectrokinetic properties readily accessible.
