## Abstract Cocyclotrimerisation of [^14^C~2~] acetylene with 2โbutyne gave [3,4,5,6โ^14^C~4~] orthoโxylene (50% overall yield based on [^14^C] BaCO~3~). 93% Nitric acid oxidation at 145ยฐC for 55 hours of the crude [3,4,5,6โ^14^C~4~] orthoโxylene gave [3,4,5,6โ^14^C~4~] orthoโtoluic acid (25% overa
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 c
