Reaction Conditions

Reaction Steps

To a mixture of lead tetraacetate (2.44 g, 5.50 mmol) and mercuric diacetate (0.16 g, 0.50 mmol), thoroughly flushed with nitrogen, is added anhydrous chloroform (6 ml). This mixture is warmed to 40° C., and 4′-chloro-4-methylbiphen-3-ylboronic acid (1.23 g, 5.00 mmol) is added in one portion, and the suspension is heated at this temperature for 5 hours. After cooling to room temperature the mixture is concentrated to a small volume, then triturated with hexanes and filtered to yield crude 4′-chloro-4-methylbiphen-3-yllead triacetate.
