| titleOfInvention | Process for the preparation of diacylated 4-imidazolin-2-ones |
| abstract | A process for the preparation of a diacylated 4-imidazolin-2-one of the formula ##STR1## wherein R 1 and R 2 independently represent hydrogen, optionally substituted alkyl, cycloalkyl, aryl and alkoxy, which comprises contacting a compound of the formula ##STR2## wherein R 1 and R 2 have the previously assigned significance with a source of chlorine at a temperature from 20° to 150° C. in the presence of a radical forming agent or under ultra-violet light and thereafter dehydrohalogenating or dehalogenating the resultant chlorinated product. n The diacylated 4-imidazolin-2-ones prepared by the process are useful for photochemical cycloadditions and as intermediates for the preparation of compounds in the biotin series. |
