Adding some certain compound to certain chemical reactions, such as: 2270-59-9, name is 5-Bromo-2-methylpent-2-ene, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2270-59-9. 2270-59-9
EXAMPLE 5 2-Methyl-5-nitro-2-pentene 5-Bromo-2-methyl-2-pentene (120 g, 0.736 m) is added dropwise to a solution of sodium nitrate (60.9 g, 0.883 m) in dimethylsulfoxide (700 ml) at room temperature under nitrogen. The mixture is stirred for 1 hour and treated with water (500 ml) and petroleum ether (1 l). The organic layer is dried (Na2 SO4) and evaporated in vacuo to give a pale yellow liquid (80.7 g). This material is purified by column chromatography on silica gel (800 g, petroleum ether) to give 2-methyl-5-nitro-2-pentene as a colorless liquid (45.4 g, 48%). ir (neat) 1550 cm-1; nmr (CDCl3) delta: 1.70 and 1.73 (both 0,6H, (CH3)2 C=C<), 2.5~2.93(m, 2H, CH2 4.35 (t, J=8 Hz, 2H, --CH2 --CH2 --NO2), STR7
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 5-Bromo-2-methylpent-2-ene.
