摘要:
An improved six-step synthesis of 5-tert-butyl-3-nitrophthalonitrile (1) is described. The title compound and all the intermediates are fully characterized spectroscopically (FT-IR, H-1 NMR, C-13 NMR, MS). In addition, single-crystal X-ray diffraction further confirmed the structure of the title compound. (C) 2013 Elsevier Ltd. All rights reserved.
