A novel process for producing an N-alkylhydroxylamine of the formula (I) rnh-oh (i) wherein R represents an alkyl group which may be substituted with least one substituent, which comprises reacting an N-mesyl-O-(p-alkoxybenzyl)hydroxylamine or an N-mesyl-O-(2,4,6-trialkylbenzyl)hydroxylamine with an alkyl halide of the formula (III) rx (iii) wherein R is as defined above and X represents a halogen atom, under a basic condition to produce the corresponding N-alkyl-N-mesyl-O-(p-alkoxybenzyl)hydroxylamine or N-alkyl-N-mesyl-O-(2,4,6-trialkylbenzyl)hydroxylamine, and treating the resulting compound with a solution of a phenol compound, and novel N-alkyl-N-mesyl-O-(p-alkoxybenzyl)hydroxyl amines and N-alkyl-N-mesyl-O-(2,4,6-trialkylbenzyl)hydroxylamines which are useful as intermediates in the above process.
一种新型的生产N-烷基羟胺(I)rnh-oh(i)的方法,其中R代表一种烷基,该烷基可以被至少一个取代基取代,包括反应N-甲磺酰-O-(对烷氧基苯甲基)羟胺或N-甲磺酰-O-(2,4,6-三烷基苯甲基)羟胺与式为(III)rx(iii)的烷基卤化物反应,其中R如上定义,X代表卤素原子,在碱性条件下生成相应的N-烷基-N-甲磺酰-O-(对烷氧基苯甲基)羟胺或N-烷基-N-甲磺酰-O-(2,4,6-三烷基苯甲基)羟胺,并用苯酚化合物的溶液处理所得化合物,以及作为上述过程中间体有用的新型N-烷基-N-甲磺酰-O-(对烷氧基苯甲基)羟胺和N-烷基-N-甲磺酰-O-(2,4,6-三烷基苯甲基)羟胺。
