Abstract

Grignard reaction of p-Br2C6H4 with R2BX (R = mesityl, X = F; R = Ph, X = Br; R2BX = 9-borabicyclo3.3.1nonyl bromide) gave p-(R2B)2C6H4 (I). Cyclic voltammetry of I (R = mesityl) (II) indicated 2 reversible redns. to the radical ion and the dianion. The redn. potentials of I were high, -1.39 V for II vs. -0.57 V for p-(O2N)2C6H4. on SciFinder(R)
