Allgemeine Beschreibung
4′-Bromo-3′-nitroacetophenone is an electron deficient acetophenone derivative.
Synthese
4'-Bromo-3'-nitroacetophenone is synthesised using 4'-Bromoacetophenone as a raw material by chemical reaction. The specific synthesis steps are as follows:
To fuming nitric acid (200 mL), l-(4- bromophenyl)-l-propanone (1-1) (40 g, 0.20 mol) was added while keeping the inside temperature of mixture at 5 to 10 0C. The reaction solution was stirred at this temperature for 30 minutes and then poured into ice. The precipitate was collected by filtration, washed with distilled water (25 mL x 2) and re-crystallized from methanol to give 1-2 (18 g, 37percent yield). 1H NMR (500 MHz, CDCl3) δ 8.38 (IH, d, J= 2.0 Hz), 7.99 (IH, dd, J= 8.2 Hz, 2.0 Hz), 7.86 (IH, d, J= 8.2Hz), 3.01 (2H, q, J= 7.1Hz), 1.25 (3H, t, J= 7.1Hz) ppm; LC-MS (ESI): m/z 244.0 (M+H)+.
