Abstract
The present invention relates to a process for preparing C-Clactams, in which a C-C-alkyl nitrite is reacted with a C-C-cycloalkane and is illuminated with a light-emitting diode during the reaction. This forms a C-C-cyclohexanone oxime which is then converted further to a C-Clactam; the C-Calcohol formed is recycled into the preparation of the C-C-alkyl nitrite.
