The process involves contacting a crude dinitrotoluene stream containing by-product nitrophenolic materials with an alkaline material and monitoring the pH such that dinitroorthocresol by-product is maintained in the organic phase while the trinitroorthocresol by-products are converted to water-soluble ...
As such, 2-azido-5-nitrophenol 5 was synthesized. As a test reaction we tried to trap the corresponding o-quinone monoamine intermediate with 1-butoxyethene in an Inverse Electron Demand Diels Alder (IEDDA) reaction (Scheme 5). For this transformation, however, no fruitful results wmeixretu...
