ABSTRACT:
A heterocyclic compound having the structural formula ##STR1## where R is C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.6 cycloalkyl, trifluoromethyl, phenyl, substituted phenyl, phenoxy, substituted phenoxy, benzyl or substituted benzyl; and R.sup.1 is at least a partially saturated monocyclic or bicyclic heterocycle of nitrogen which may be substituted with lower alkyl and physiologically acceptable salts thereof is disclosed. A process for forming this compound which involves the reaction of an amine of the formula HR.sup.1 where R.sup.1 has the meanings given above with a substituted 2-propenyl halide having the structural formula ##STR2## where R has the meanings given above; and X is a halogen atom is described. The invention embodies the above-mentioned novel 2-propenyl halide utilized as an intermediate in the formation of the heterocyclic compound of this invention. A method ofcontrolling phytopathogenic fungi by applying a fungicidally effective amount of the heterocyclic compound of the present invention to the locus under attack by said fungi is also taught. Finally, a fungicidally composition comprising the heterocyclic compound of the present invention and a suitable carrier therefor is set forth.
