## Abstract 3,5‐Dinitropyridine and some of its derivatives are aminated with a liquid ammonia solution of potassium permanganate to the corresponding 2‐, 4‐ and 6‐ mono‐ and (or) di‐ and (or) triamino‐substituted compounds. The intermediate amino σ‐adducts of 3,5‐dinitropyridines are detected by ^

## Abstract Reaction of 6‐chloro‐ and 6‐(methylthio)purine with potassium amide in liquid ammonia leads to the formation of adenine. When these aminations are carried out with ^15^N‐labelled potassium amide, the ^15^N label is found to be present in the amino group, proving that these reactions do
