Participants

Reaction Conditions

Reaction Steps

To a solution of lead tetraacetate (4.3 g, 9.7 mmol) in dry chloroform (15 ml) at 40° C. is added 3,5-dimethylbiphen-4-ylboronic acid (2.0 g, 8.8 mmol) in one portion under an atmosphere of nitrogen. The reaction mixture is stirred at 40° C. for 4 hours, and then is cooled to room temperature and filtered, washing the residual solid with chloroform (50 ml). The filtrate is filtered through a plug of potassium carbonate supported on diatomaceous earth and the filtrate is evaporated under reduced pressure to afford 3,5-dimethylbiphen-4-yllead triacetate as a brown oil (3.37 g).
