New research progress on 78593-33-6 in 2021. 78593-33-6,Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments.In an article, Which mentioned a new discovery about78593-33-6 Name is 3-Bromocinnoline.
(a) 3-(4-Hydroxybenzenesulphonyl)cinnoline A mixture of 2.1 g (0.01 mol) of 3-bromocinnoline, 6.6 g (0.02 mol) of sodium 4-tosyloxybenzenesulphinate and 50 ml of dimethylsulphoxide was stirred and heated at 120 C. for 24 hours. The mixture was poured into water and extracted with dichloroethane. The dichloroethane solution was washed with water, dried on anhydrous sodium sulphate and filtered. The solvent was then evaporated with a rotatory evaporator to provide 2.5 g of an oily residue. The desired product was then isolated by chromatography on a silica column using dichlorethane/methanol 98/2. In this manner, 0.45 g of 3-(4-hydroxybenzenesulphonyl)cinnoline was obtained. Yield: 10.2%
Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 3-Bromocinnoline.78593-33-6
