## Abstract A continuous three‐step micro‐synthesis of 1,2‐dibromo‐3‐chloropropane, labelled with tritium in position 1 and 2, is described. A specific activity of 10.8 Ci/mmol is obtained. The yield observed in the uninterrupted overall synthesis is appreciably lower than that in the controlled st

## Abstract An improved synthesis of [^15^N] labelled acetamide and acetonitrile is described which provides these compounds in yields of 85% and 64%, respectively. The key difference in the present preparation is the use of 2,2,2‐trifluoroethyl acetate for the reaction with ^15^NH~4~OH.

## Abstract Toluene derivatives are often found in drug‐like molecules, and are therefore desirable as radiolabelled moieties. The desire for an alternate to the Stille coupling led us to investigate the feasibility of the Suzuki coupling. We have found the Suzuki coupling route to be a robust alte
