The [2 + 4] Diels−Alder Cycloadditon Product of a Probable Dialuminene, Ar‘AlAlAr‘ (Ar‘ = C6H3- 2,6-Dipp2; Dipp = C6H3-2,6-Pri2), with Toluene
摘要:
Reduction of Ar'AlI2 (Ar' = Ar'= C6H3-2,6-Dipp2; Dipp = C6H3-2,6-Pri2) with KC8 in diethyl ether most probably affords the first "dialuminene", Ar'AlAlAr'; it was characterized by its reaction with toluene which yielded a [2 + 4] cycloaddition product incorporating the Ar'AlAlAr' unit.
