New S-aryl-cyan:imido-thio cpds. - useful as bactericides and fungicides

S-aryl-cyanimidothio cpds. of formula (I) are new. In (I) R1, R2 = H, 1-10C alkyl, alkoxy, CN, halo, CF3, NO2, SO2NH2 or dialkylamino or R1+R2 = a 2,3-(CH)4 gp., thus forming an ortho-fused benzene ring, R3 = H, halo or lower alkyl, X = O, S or NH, R4 = (a) when X = S, R4 is a lower alkyl gp. or an...

Summary:S-aryl-cyanimidothio cpds. of formula (I) are new. In (I) R1, R2 = H, 1-10C alkyl, alkoxy, CN, halo, CF3, NO2, SO2NH2 or dialkylamino or R1+R2 = a 2,3-(CH)4 gp., thus forming an ortho-fused benzene ring, R3 = H, halo or lower alkyl, X = O, S or NH, R4 = (a) when X = S, R4 is a lower alkyl gp. or an aryl gp. (opt. substd. by R1, R2 and R3), (b) when X = O, R4 = a lower alkyl gp., (c) when X = NH, R4 = a lower alkyl gp. or opt. substd. aryl. Cpds. (I) are obtd. by reacting a cpd. of formula (II) with a cpd. of formula (III). In the formulae, M = alkali metal esp. Na or K. The gp. R4'X' = (a( MS or alkylthio, (b) alkoxy or (c) alkylamino or opt. substd. arylamino and A = a mineral acid anion. Reaction is in the presence of Cu powder at 0-30 deg.C. USE/ADVANTAGE - (I) are bactericides and fungicides which may be used against Erwinia carotovorum, Pseudomonas phaseo yeasts, Phytophora infestans, Botrytis cinerea, Pyricula oryzae or Plasmopora viticola.
