<p>Cpds. of fomrula (I): X-N=N-NR1R2 (where X is (Y)n-substd. phenyl or 1-naphthyl; Y = H, Me, MeO or Cl; n = 1 or 2 and when n = 2 Y can be the same or different; R1 and R2 are lower alkyl or allyl or together form an N-contg. opt. Me-substd. heterocyclic gp. which can contain 4-6C polymethylene groups) are antivirals, insecticides and miticides (I) may be prepd. by diazotising XNH2 and reacting with HNR1R2 in the presence of a diluent and an acid binder.</p> |
