heteroaromatic compounds with 3-methyl substituted 2-quinonyl boronic acids proceeded by 1,4-addition followed by spontaneous protodeboronation, leading directly to the Friedel−Crafts alkylation products instead of the commonly observed alkenylation derivatives resulting from quinones. The boronic acid acts as a temporary regiocontroller, making the system a highly reactive quinone equivalent and opening a

A novel class of 3-halo-1H-indol-4-amine derivatives, particularly for dyeing keratin fibers, the azomethine dyes formed from them, their uses as a coupler for dyeing keratin fibers, hair dyeing compositions comprising them, method of dyeing hair thereof, and a hair dyeing kit thereof are disclosed. The products of the oxidative coupling with hair dye primary intermediates, particularly pyrazole derivative, a p-phenylenediamine derivative, a p-aminophenol derivative, have improved fastness properties over currently used violet-blue to blue azomethine dyes.
