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 step‐by‐step synthesis.

## 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.
