    Abstract: Oxadiazoles of formula (I): are prepd. by reacting acylamidine salts (II) first with a hypohalite (III) MOX and secondly with a NH4 or alkali(ne earth) cpd. in presence of a solvent. In the formulae R1 and R2 are each H, aliphatic, cycloaliphatic araliphatic, aromatic or heterocyclic gps. or R3NH; R3= aliphatic or aromatic gp. and R2 may also be (R3)2N or R3O; X is halo and M is a cation esp. Na or K. (I) are inters. for dyes, pesticides, optical brighteners and pharmaceuticals, Some have insecticidal, fungicidal, herbicidal, antibacterial, anti-inflammatory, sedative, convulsive and coronary-dilating activity.

    Abstract: Novel 1,3-dioxan-5-yl-alkenyltriazoles of the formula I where R1 and R2 are identical or different and each is hydrogen or alkyl of 1 to 5 carbon atoms, Ar is furanyl, thienyl, biphenylyl or naphthyl, or is phenyl which is unsubstituted or substituted by alkyl, alkoxy or alkenyl, each of 1 to 5 carbon atoms, or by fluorine, chlorine, bromine, iodine, nitro, trifluoromethyl or phenoxy, and X is C=O, -CH(OH)- or -CH(O-COR3)-, where R3 is unsubstituted or halogen- or alkoxy-substituted alkyl of 1 to 5 carbon atoms or alkenyl of 2 to 5 carbon atoms or aryl, their salts and metal complexes, and their preparation. The novel compounds are plant growth regulators.
