✦ Synopsis

A safe procedure for the conversion of barium carbonate-I4C to potassium cyanide-I4C on a 6-7 mmol scale in 90-98% yield was developed. Barium carbonate-14C was heated with excess potassium azide in a matrix of sand without added potassium metal, allowing safe, rapid and convenient recovery of the cyanide.
