Gold Catalyzed Decarboxylative Cross-Coupling of Iodoarenes

This report details a decarboxylative cross-coupling of (hetero)aryl carboxylates with iodoarenes in the presence of a gold catalyst (>25 examples, up to 96% yield). This reaction is site specific, which overcomes prior limitations associated with gold catalyzed oxidative coupling reactions. The reactivity of the (hetero)aryl carboxylate correlates qualitatively to the field effect parameter (Fortho). Reactions with isolated gold complexes and DFT calculations support a mechanism proceeding through oxidative addition at a gold(I) cation with decarboxylation being viable at either a gold(I) or a silver(I) species.

Synthesis of biaryls by Pd-catalyzed decarboxylative homo- and heterocoupling of substituted benzoic acids

By carefully choosing the right substrate ratio, catalyst combination, and base, symmetrical and unsymmetrical biaryls can be readily synthesized through the Pd-catalyzed decarboxylative homo- and heterocoupling of substituted benzoic acids. The reaction gave the desired products in 40-90% yield and is compatible with 2-nitro-, 2-methoxy-, 2-fluoro-, and 2-chloro-substituted benzoic acids. With the correct substrate ratio, catalyst combination, and base, symmetrical and unsymmetrical biaryls can be readily synthesized through the Pd-catalyzed decarboxylative homo- and heterocoupling of substituted benzoic acids.

Synthesis, NMR spectroscopic characterisation and reactions of 2,6-difluorophenylxenon fluoride, 2,6-F2C6H3XeF

[2,6-F2C6H3Xe][BF4] is quantitatively transferred into 2,6-F2C6H3XeF in reactions with [NMe4]F. The latter has been isolated as a colourless solid which is stable in dichloromethane solution at room temperature for approximately 1 h. 2,6-F2C6H3XeF readily reacts with Me3SiX (X = Cl, Br, CN, NCO, OCOCF3, OSO2CF3, C6F5, 2,6-F2C6H3) to give compounds of general compositions 2,6-F2C6H3XeX which were identified by multinuclear NMR experiments. Evidence was found for C6H5Xe(2,6-F2C6H3) as a product of the reaction with C6H5SiF3.
