Process for the preparation of cyclic N-azidosulfonylarylimides |
| abstract |
Process for the preparation of a photoinitiator from the group of the cyclic N-azidosulfonylarylimides of the formula where Ar is a phenylene or naphthylene radical and where the radicals R1 and R2 can be identical or different, are hydrogen or saturated aliphatic hydrocarbon radicals and can be part of a ring, characterized, that a chlorosulfonation of the corresponding cyclic arylimides to the corresponding sulfonyl chlorides and then a reaction of the sulfonyl chlorides with sodium azide and / or other alkali azides to give the cyclic N-azidosulfonyl arylimides is carried out. |
