1-benzisoxazolium tetrafluoroborate (1a) gives the title nitrenium ion 2a. Under direct photolysis of 1a, in the presence of nucleophiles (i.e. ROH), quinone imine ethers such as (6) are the major product. Triplet sensitized irradiation gives both 6 and the parent amine 5.
邻氨基苯甲酸盐,5-甲基-3-N-叔丁基-2,1-苯并恶唑鎓四氟硼酸盐(1a)的光解得到标题的ion离子2a。在1a的直接光解下,在亲核试剂(即ROH)存在下,醌亚胺醚(如(6))是主要产物。三重态敏化辐射既得到6,又得到母体胺5。
