Question

A catalyst is used in a sub-stoichiometricacmount. A common way to quantify the catalyst: limiting reactant ratio in a catalytic reaction is to quote the amount of catalyst used in mol%. For example 2 mol % means that the reaction useds 2% as much catalyst as limiting reactant. Showing all work, calculate the mol % of Pd used inthe Suzuki-Miyaura reaction. I have wrote down above the amount amount of mols used in the reation for the arylboronic acid and the aryl bromide. The amount of Pd used is 1 mg/ml.

Explanation / Answer

The reagents used in the  Suzuki-Miyaura reaction are as follows:

Arylboronic acid = 0.00105 mols = 1.05 mmol

Aryl bromide = 0.001 mols = 1 mmol

Pd = 1 mg/ml = 1/106.42 = 0.00939 mmol

So, Mol% of Pd = 0.939
