| titleOfInvention | Method for the preparation of a N-alkoxy-(tetra-or hexahydro)-phthalimide and method for the preparation of a N-alkoxyamine |
| abstract | Method for the preparation of N-alkoxy-(tetra- or hexahydro)-phthalimide according to formula I ##STR1## R 1 being methyl or ethyl and R 2 and R 3 being each independently of one another hydrogen or alkyl with 1-4 C atoms or R 2 and R 3 together with the carbon atom to which they are bonded forming a ring with 5 or 6 C atoms, wherein the salt of the corresponding N-hydroxy-(tetrahydro- or hexahydro)-phthalimide according to formula II: ##STR2## with R 2 and R 3 as defined above and M being an alkali metal, is brought into contact with R 1 Cl as alkylating agent, wherein R 1 has the aforementioned meaning. n The N-alkoxy-(tetra- or hexahydro)-phthalimide can afterwards be converted with the aid of hydroxylamine sulphate into the corresponding alkoxyamine after which the alkoxyamine obtained can be isolated. In this manner a simple and commercially attractive process for the preparation of O-(m)ethylhydroxylamine can be implemented. |
