General procedure: To 64.3 mg (0.278 mmol) of TTbQ-Me dissolved in anhydrous acetone (20 ml) in a two necked flask, 30 mg (0.278 mmol) of p-benzoquinone and 120 mg (0.116 mmol) of Pd2DBA3CHCl3 were added in sequence under inert atmosphere (Ar). The resulting mixture was stirred in the dark for 30 min, filtered on a celite filter and evaporated under vacuum to a small volume. Addition of Et2O induces the precipitation of the complex which was filtered off and dried in a desiccator for 5 h. 82.2 mg of the title compound as a red solid were obtained (yield 80percent).
