visible‐light‐mediated carbonylative amidation of aryl, heteroaryl, and alkyl halides. A tandem catalytic cycle of [Ir(ppy)2(dtb‐bpy)]+ generates a potent iridium photoreductant through a second catalytic cycle in the presence of DIPEA, which productively engages aryl bromides, iodides, and even chlorides as well as primary, secondary, and tertiary alkyl iodides. The versatile in situ generated catalyst is compatible
The invention is directed to a cosmetic composition and the precursor thereof. The composition has solid agent and liquid agent, both of which are cosmetic benefit ingredients. The solubility of solid agents in liquid agents in the inventive compositions is enhanced in the presence of a tricyclodecane amide.
