Novel Synthesis of Diazetidine-2,4-dione by Ring Expansion of Diaziridinone
摘要:
Treatment of N,N'-di-tert-butyldiaziridinone with Ni(CO)(4) under an atmosphere of carbon monoxide caused a carbonylative ring expansion to give di-tert-butyldiazetidinedione in good yield. In the presence of diphenylketene under the conditions, azetidinedione derivative was obtained.
