ABSTRACT:
Various alkyl 4-[o-(substituted methyleneamino)phenyl] 3-thioallophanates are useful as fungicides and mite ovicides.
The compounds are prepared by reacting alkyl 4-(o-aminophenyl)-3-thioallophanates with aldehydes or trialkyl orthoformates. Some of the compounds are prepared by further reacting the reaction product of an alkyl 4-(o-aminophenyl)-3-thioallophanate and a trialkyl orthoformate with a primary or secondary amine.
Exemplary species are methyl 4-[o-(o-fluorobenzylideneamino)phenyl]-3-thioallophanate, methyl 4-[o-(4-methylbenzylideneamino)phenyl]-3-thioallophanate and methyl 4-[o-(2-furfurylideneamino)phenyl]-3-thioallophanate.
