Resorufin-Catalyzed PhotoATRP Under Red Light.
The sodium salt of resorufin (RSF), an inexpensive, water-soluble, commercially available phenoxazinone dye, serves as an efficient photocatalyst for low-copper dual-catalysis PhotoATRP across the visible spectrum. RSF loadings as low as 1 ppm catalyzed PhotoATRP of acrylates in the presence of CuBr2/Me6TREN, yielding...
