Zusammenfassung

Verdazyle mit einer Methylenbrücke in 6-Stellung werden in Gegenwart von Carboraffin durch Luftsauerstoff unter Ringöffnung zu N-Formyl-formazanen oxydiert. Mit Acetanhydrid/BF3-Ätherat ergeben C-Aryl-formazane C-Aryl-N-Acetyl-formazane.

Abstract

In the presence of carboraffin verdazyls with a methylene bridge in position 6 are oxidized with atmospheric oxygen under ring opening to N-formyl-formazans. C-Aryl-formazans yield C-aryl-N-formyl-formazans with aceticanhydride/BF3 etherate.
