The first example of ancillary (P,N)-ligand-enabled gold-catalyzed C-N cross-coupling reactions of aryl iodides with amines is reported. The high generality of the reaction in de novo synthesis, late-stage modifications, and cascade processes to access functionalized indolinones and carbazoles underscores the synthetic potential of the presented strategy. Monitoring the reaction with ESI-HRMS and NMR provided strong evidence for the in situ formation of putative high valent Au(III) intermediates.

4-Isothiocyanato-4'-nitrodiphenylamine (amoscanate)(1a), an anthelmintic drug now under clinical trials, has been synthesized by the base-catalysed reaction of p-nitrophenol with either p-isothiocyanatophenyl isocyanate or 1,4-phenylenediisothiocyanate.
