Abstract
5,5′‐Bi‐1,2,4‐triazinyl compounds are obtained by the treatment of 5‐unsubstiluted 1,2,4‐triazines with either sodium methoxide or with aqueous potassium cyanide.5,5′‐Bi‐1,2,4‐triazinyl is also obtained by the reaction of 1,2,4‐triazine with potassium cyanide.It is proposed that the sodium methoxide catalyzed dimerizations occur via a carbanionic intermediate; the aqueous potassium cyanide catalyzed reactions via a cyanide addition product and the potassium in liquid ammonia reaction via a free radical dimerization process.
