s-Triazines. Part I. Synthesis and reactions of dihalogeno-heteroaryl-s-triazines
Abstract
Metallated derivatives of substituted or unsubstituted furans, thiophens, and pyrroles react with 2,4,6-trichloro-s-triazine (cyanuric chloride) to produce the corresponding 2,4-dichloro-6-(heteroaryl)-s-triazines. The effect of electrophilic substitution (nitration and bromination) on such ring systems is described.
