摘要

The common feature of all these rearrangements is a pivotal nitrogen atom that probably suffers minimal change in geometry during the molecular transition. Recently the possibility of using carbon as the pivotal atom in a BKR has been considered theoretically 3 and it was concluded that with suitable substituents (eg an alkoxy or dialkylamino group) attached to the 5-position of 4-nitroso-2,1-benzisoxazole, such a rearrangement might be energetically possible ...
