Aplicação

4,N,N-Trimethylaniline is a tertiary amine that can undergo iron-catalyzed oxidative C-C coupling with phenylacetylene and benzamide in the presence of tert-butylperoxide to form N,4-dimethyl-N-(3-phenylprop-2-ynyl)benzenamine and N-((methyl(p-tolyl)amino)methyl)benzamide, respectively.

Resin composites are widely used in dentistry, and are polymerized in situ using a blue-light activated, free-radical polymerization mechanism. Blue light (400-500nm) is used to activate camphoroquinone (CQ), which decomposes to form free radicals that are stabilized by dimethyl-p-toludine (DMPT).

There is an increasing need to develop new biomaterials as tissue engineering scaffolds. Unfortunately, many of the materials that have been studied for these purposes are polyesters that hydrolytically degrade into acidic products, which may harm the surrounding tissue, and

The polymerization initiators for resins cured using visible light usually consist of a photosensitizer, primarily camphorquinone (CQ), and a reducing agent, which is often a tertiary amine (DMPT, DMAEMA), while the initiator used for self-curing resins consists of benzoyl peroxide
