Gold-Catalyzed Oxidative Cross-Coupling Reactions among Two Distinct Arenes and One Gold Carbene with Phosphoric Acids as Cocatalysts

Gold-catalyzed oxidative cross-coupling reactions of two distinct arenes with one gold carbene furnish triarylmethane products. Notably, competitive homo-coupling reactions are efficiently suppressed with a phosphoric acid as co-catalyst (10 mol%) in THF. These cross-coupling reactions have a wide scope of applicable substrates, with respect to indoles, arylamines, and α-aryl diazo cyanides or esters. Our mechanistic analysis indicates that the basicity of the arylanilines greatly affects the cross-coupling efficiency. (Figure presented.).

The photochemical reactions of crystal violet leuconitrile (CVCN) were investigated by the means of product analysis and trapping experiments, laser flash and steady-state photolysis, and steady-state fluorescence. The influence of oxygen on the reaction was examined in detail. The photochemistry of malachite green leuconitrile (MGCN), basic fuchsin leuconitrile (BFCN), and crystal violet leucomethyl (CVMe) and leucobenzyl (CVBn), as well as triphenylacetonitrile, was studied. The results suggest ionization occurs from S1, while the di-π-methane reaction is the photochemical route from T1.
EFFECT OF STRUCTURAL FACTORS ON THE KINETICS OF THE REACTION OF THE CONJUGATE IONS OF THE TRIARYLMETHANE SERIES WITH THE CYANIDE ION

The kinetic of the raction of some triarylmethane dyes with the CN(1-) ion in aqueous solution in the range of 11.5-50 deg C were investigated by a spectrophotometric method.A correlation analysis of the results was undertaken, and on the basis of a comparison of the obtained characteristics with the corresponding parameters for the formation of triarylcarbinols it was shown that the type of control of the reactivity of the conjugate ions is independent of the nature of the nucleophilic agent.
