    • 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.
    • 一种制备式(I)的N-烷基羟胺的新方法RNH-OH(I)其中R表示可以被至少一个取代基取代的烷基,其包括使N-甲磺酰基-O-(对 - )羟胺或N-甲磺酰基-O-(2,4,6-三烷基苄基)羟胺与式(III)的卤代烷(其中R如上定义,X​​表示卤素原子)的式 制备相应的N-烷基-N-甲磺酰基-O-(对 - 烷氧基苄基)羟胺或N-烷基-N-甲磺酰基-O-(2,4,6-三烷基苄基)羟胺的条件,并将所得化合物用 酚化合物的溶液和新的N-烷基-N-甲磺酰基-O-(对 - 烷氧基苄基)羟胺和N-烷基-N-甲磺酰基-O-(2,4,6-三烷基苄基)羟胺,其可用作 中间体在上述过程中。
