摘要:
Mes(2)BF and Ar(2)(N)BF (Ar(N) = 4-(Me(2)N)-2,6-Me(2)-C(6)H(2)) react with trimethylsilyltriflate and p-dimethylaminopyridine in chlorobenzene to afford the corresponding borenium salts [Mes(2)B-DMAP](+) OTf(-) ([1](+)OTf(-)) and [Ar(2)(N)B-DMAP](+) OTf(-)([2](+)OTf(-)), which have been fully characterized.
