General Description

It′s an aryl boronate ester. Arylboronic acids may be prepared by hydrolysis of boronate esters, and consequently many other boronic acid derivatives (e.g., organotrifluoroborates) are derived.

Pd(II)-catalyzed base-free oxidative homocoupling of fluorene diboronic acid ester: A new approach for the synthesis of π-conjugated polymers

A new route, Pd(II)-catalyzed base-free oxidative homocoupling, has been successfully used for the synthesis of polyfluorene. Using only diboronic esters and a stable Pd(II) catalyst in the absence of base can greatly simplify the synthetic condition of conjugated polymers.
