Abstract
Friedelin oxime (1) on prolonged heating with selenium dioxide in diox an furnishes three products identified as 2-keto-friedel-3(4)-en-3-azo -23-N-selenide (2), friedel-1(10),4(23)-dien-3-nitroso-O-23-selenoxide (3) and 2-keto-3-oximino friedel-1-selenoxide (4) while similar react ion on cerin oxime (5) affords a single compounds 3.
