Reaktionsschritte

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 mixture is stirred at 40° C. for 4 hours, and then is cooled to room temperature. The precipitate is removed by filtration, and the filtrate is then passed through a plug of potassium carbonate supported on diatomaceous earth to remove acetic acid. The filtrate is evaporated in vacuo to afford 3,5-dimethylbiphen-4-yllead triacetate (3.37 g) as a brown oil.
