TECHNOLOGY FOCUS - AGRICULTURE - Preferred Composition: The composition comprises a surfactant and co-solvent. The composition includes a fungicide, a herbicide and/or a pesticide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Preparation of (AA) comprises: reacting alpha -aminoketone compounds of formula (a) with carbon disulfide in the presence of sodium carbonate in ethanol to obtain the corresponding oxazole-2-thiol compounds of formula (b); converting thiol group of (b) to chlorine with phosphorustrichloride in the presence of triethylamine at higher temperature to give corresponding oxazole-2-chloro compounds of formula (c); and reacting (c) with pyrrole compounds of formula (d) (after treatment with sodium hydride) at higher temperature to give 2-pyrrol-5-substituted oxazole compounds of formula (e) (representative compound of (AA)). ACTIVITY - Nematocide. The nematicidal activity of (AA) was tested against Meloidogyne incognita in cucumber using root-knot nematode greenhouse soil assay. The results showed that the nematicidal activity of 5-(4-chlorophenyl)-2-(1H-pyrrol-1-yl)oxazole was 100%.    MECHANISM OF ACTION - None given.    ADMINISTRATION - Administration of the composition is oral, topical or by injection. Application of the composition is drenching or dripping. No dosage details given.    SPECIFIC COMPOUNDS - 7 Compounds (AA) are disclosed e.g. 5-(4-chlorophenyl)-2-(1H-pyrrol-1-yl)oxazole of formula (AAa), 5-(4-chlorophenyl)-2-(thiophen-2-ylmethyl)oxazole, 3-(4-chloro-phenoxy)-5-furan-2-yl-(1,2,4)oxadiazole, 3-(4-chloro-phenyl)-5-furan-2-ylmethyl-(1,2,4)oxadiazole and 3-(4-chlorophenyl)-5-(1H-pyrrol-1-yl)-1,2,4-thiadiazole.    EXAMPLE - A mixture of 2-bromo-1-(4-chlorophenyl)ethanone (1 equivalent) and sodium diformylamide (1.1 equivalent) in acetonitrile (1.5 ml per mmole) was heated to reflux for 4 hours at 105 degrees C. The formed sodium bromide was removed by filtration and the filtrate was concentrated in vacuum. The residue was dissolved in ethanol (2.5 ml per mmole) and concentrated aqueous hydrochloric acid (0.9 ml per mmole) was added at ambient temperature. After stirring for 72 hours at room temperature, the solids were worked up to give 2-amino-1-(4-chlorophenyl)ethanone hydrochloride. 2-amino-1-(4-chlorophenyl)ethanone hydrochloride (3.88 mmole) and carbon disulfide (7.76 mmole) were suspended in ethanol (10 ml). To the above mixture, a solution of sodium carbonate (4.08 mmole) in water (4 ml) was slowly added at ambient temperature, and heated to 80 degrees C for 18 hours. Then the mixture was cooled and filtered and the filtrate was worked up to give 5-(4-chlorophenyl)oxazole-2-thiol. Pyrrole (2 ml) was treated with sodium hydride (0.22 mmole, 55% wetted with mineral oil), and added with 7S-(4-chlorophenyl)-2-(1H-pyrrol-1-yl)oxazole (0.21 mmole). The mixture was heated to 60 degrees C for one hour, 85 degrees C for 6 hour and 100 degrees C for 6 hour. More sodium hydride (0.22 mmole, 55% wetted with mineral oil) was added and the reaction mixture was heated to 120 degrees C for 6 hours. The mixture was evaporated to dryness in vacuo and partitioned between aqueous saturated ammonium chloride and ethyl acetate, and the obtained solution was worked up to give 5-(4-chlorophenyl)-2-(1H-pyrrol-1-yl)oxazole (72.4 mole, purity 98.6%).
