The omission of the potassium acetate, reported to be needed for decomposition of BSA, did not alter the outcome of the alkylation after conventional heating, nor after microwave irradiation at power input up to 120 W. At a microwave power of 500 W, the addition of very small amounts of potassium acetate allowed for full conversion using 3a as ligand. An 85% yield was encountered in absence of potassium acetate under otherwise identical conditions. No effect of potassium acetate was observed when using 3b as ligand. The ee values were not affected by the addition of potassium acetate nor were the temperature profiles.
