Bromination of Alkenes
The two most common halogenation reactions are chlorination and bromination. The addition of these halogens to alkenes yields 1,2-dihalides. Chlorinations reactions are used to synthesize over 6 million tons per year of ethylene dichloride (1,2-dichloroethane) for use as a solvent and for subsequent polymerization to produce poly(vinylchloride) known more commonly as PVC which is used for plumb...
متن کاملMulti-bromination of 1,8-dihydroxy-9- anthrone, important intermediates in the synthesis of antipsoriatic drugs
10-bromo-1,8-dihydroxy-9-anthrone (10-bromoanthralin) was synthesized with precise ratio of bromine to anthralin (1.10:1), respectively. With this ratio of the reagents, the reaction is repetitive at any scale. This compound is a highly significant intermediate for the synthesis of many anthralin derivetised antipsoriatic drugs. Bromination at both benzylic and aromatic ring positions of anthra...
متن کاملSelective Mono Bromination of 1,4-Dihydropyridines
2-monobromomethyl 1,4-dihydropyridines is selectively synthesized by bromination of the parent compound by 1.1 equivalents of pyridinium bromide perbromide in dichloromethane/pyridine at -20 °C. The same reagent in dichloromethane at 0 °C produce the 2,6-bis(bromomethyl) 1,4-dihydropyridines.
متن کاملUnusual growth characteristics of a methionine-cyano-B12 auxotroph of Escherichia coli.
Escherichia coli K-12, strain AB1172, substrain 2276, a methionine(-)-cyano-B(12) (-) auxotroph grew poorly when placed in a medium containing optimal levels of cyano-B(12) and suboptimal amounts of l-methionine. A marked depression of N(5,10)-methylene-H(4)-folate reductase was observed in the inhibited cells, although no significant alterations in other enzymes involved in the metabolism of N...
متن کامل9-Ethyl-10-methylacridinium trifluoromethanesulfonate
In the mol-ecule of the title compound, C(16)H(16)N(+)·CF(3)SO(3) (-), the central ring adopts a flattened-boat conformation, and the two aromatic rings are oriented at a dihedral angle of 3.94 (2)°. In the crystal structure, weak inter-molecular hydrogen bonds link the mol-ecules. There are π-π contacts between the aromatic rings and the central ring and one of the aromatic rings [centroid-cen...
