( long chain quaternary ammonium salts) such as cetyl trimethyl ammonium bromide; cation exchanger and positively charged proteins such as protamine 0 protein. The N-sulfate groups in Heparin structure are closely related with the anti-clotting effect which will be reduced if the N-sulfate groups ...
They are used to ehnance the efficiency of the formation of Wittig adducts from less reactive chlorides and bromides. Appropriate prepartions find use as a nutrient supplement. Sodium iodide is used as the precursor to the control agent in ab initio emulsion polymerization. Sodium iodide finds ...

Other methylating agents may be used in place of methyl sulfate, e.g., an equimolar amount of methyl iodide, bromide or chloride, using the same conditions, or methyl trifluoromethylsulfonate or trimethyloxonium trinitrobenzenesulfonate. The solvent in the latter two reagents is dimethyl ether-...
An alternative way of making cephapirin is the acylation of 7-aminocephalosporanic acid by bromoacetyl bromide, which gives a bromoacetyl derivative (32.1.2.5), and which is then reacted with 4-mercaptopyridine in the presence of triethylamine, forming the desired cephapirin (32.1.2.4). View ...
To a degassed suspension of 3-(2-(7-chloro-2-quinolinyl)ethenyl)benzaldehyde (0.34 mol) in toluene (700 mL) at 0°C was added 1.0 M vinylmagnesium bromide in toluene/THF (370 mL). After stirring for 1 hour at 0°C, the reaction was quenched by the addition of saturated NH4Cl ...
325–327 The proposed mechanism involves three steps: (1) single-electron transfer from the thiolate to the initiator to form an aryl radical and a Cu2+ ion; (2) growth of the chain by radical-anion coupling; and (3) expulsion of bromide with formation of a new terminal aryl radical. ...
