Ring Expansion,Photoisomerization, and Retrocyclization of 1,4,2‐Diazaboroles |
|
| Abstract: | Diverse skeletal transformations of 1,4,2‐diazaboroles through ring expansion, photoisomerization, and retrocyclization led to the isolation of various B,N‐dihydroindole (compounds 3 and 6 ), 1,3‐azaborolidin‐2‐imine (compound 7 ), and 1,4,2‐diazaborol‐3‐imine derivatives (compound 11 ). |
