Tentacled aromatics: from central-ring to outer-ring iron sandwich complexes
Abstract
Hexamethoxyphenylethylbenzenes synthesized by hexaalkoxybenzylation of C6Me6viatheir complexation to the Fe(C5H5)+ electron-withdrawing group are readily cleaved by BBr3 to yield hexaphenols, leading to hexa- and hepta-iron sandwich complexes with six equivalent redox centres.
