| Research Abstract |
Reduction of aluminum trichloride-N-heterocyclic carbene adduct with lithium naphthalenide afforded dichloroaluminum radical, the formation of which was evidenced by a trapping experiment. Reduction of N-heterocyclic carbene adduct of dichloroalumane bearing a bulky silyl substituent provided an unexpected compound through migration of an aluminum moiety and elimination of a substituent on the nitrogen atom. Debrominative reactions of1,2-bis(phenylseleno)benzene dibromide with tribromoborane and Ag reagents gave bromoselenonium cation and unexpected selenanthrenium cations, respectively.
