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.

, (2008/06/13)
A hair dye composition comprising a fluid direct-dye hair dye vehicle suitable for application to human hair containing a tinctorially effective amount of a hair dye of formula: SPC1 In which: A. R is an electron donor functional group; B. y is a whole number from 0 to 1 inclusive; and C. x is a whole number from 1 to 2 inclusive. Also describes a method of dyeing hair using these compositions and further describes certain novel nitrodiphenylamine dyes.
