METHOD FOR PREPARING LACTAMS COMPRISING PHOTONITROSATION STEP FOLLOWED BY BECKMANN TRANSPOSITION

Title:

METHOD FOR PREPARING LACTAMS COMPRISING PHOTONITROSATION STEP FOLLOWED BY BECKMANN TRANSPOSITION

Document Type and Number:

Japanese Patent JP2017081987

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method for preparing lactams through photonitrosation of a cycloalkane using nitrosyl chloride (NOCL).SOLUTION: The photonitrosation is carried out by means of LEDs emitting a monochromatic light. Beckmann transposition/dechlorination of oxime hydrochloride generated during the photonitrosation is preferably carried out in a glass microreactor.SELECTED DRAWING: None
