Alkyl halidetertiary aminefree radical polymerizationinitiationmechanismA series of combinations of alkyl halide with tertiary amine such as ethyl α-bromophenylacetate/tris[2-(dimethylamino)ethyl)]amine (αEBP/Me6TREN), ethyl 2-bromoisobutyrate/triethylamine (EBiB/TEA), and ethyl 2-chloropropionate/ ...
Alkyl Halide Structure As mentioned, the alkyl halide structure differs from alkanes due to the replacement of a hydrogen atom with a halogen atom. The structure can be classified as primary, secondary, or tertiary, based on the number of carbon atoms bonded to the carbon bearing the halide. ...

This reaction, called the Hofman elimination, is quite analogous to the dehydrohalogenation of analkylhalide. 这个反应称为Hofman消除反应, 它很像卤代烷的脱卤化氢反应. 辞典例句 These derivatives are readily obtained by alkylation of 2 - mercaptopyridine andalkylhalides under alkaline conditions. ...
The reaction of analkyl halidewith ammonia often leads to a mixture of primary, secondary, andtertiary amineswhere more than one alkyl halide molecule has reacted with a single ammonia. Selective formation of theprimary aminemay be possible if the alkyl halide is soluble in the presence of a ...
can then undergoes N-alkylation with an alkyl halide to form the alkyl aryl amine product7. Indeed, it was found that in the absence of an alkyl halide, 4-nitrotoluene was reduced under the coupling conditions to form 4-methylaniline, albeit in a modest yield (Fig. 7a). However, 4-...
an aliphatic secondary amine to convert at least a substantial proportion of the primary halide into a tertiary amine and/or a hydro halide salt thereof which is then separated from the mixture of the non-converted propor tion of the primary alkyl halide and non verted secondary alkyl halide. ...
A color photographic silver halide light-sensitive material containing a colorless photographic cyan color-forming coupler having, in a position for coupling with the oxidation product of an aromatic primary amine developing agent, a cou...
