摘要:
Certain benzoyl chloride phenylhydrazones have been found to be active against insects and mites. The benzoyl ring and the phenylhydrazone ring can be substituted with a halogen atom, a nitro group, or an alkyl group of from 1 to 6 carbon atoms, inclusive. A new class of pentahalobenzoyl chloride phenylhydrazones is described, particularly pentafluorobenzoyl chloride phenylhydrazones. The compounds are prepared by reacting a benzoic acid phenylhydrazide with phosphorus pentachloride to obtain a benzoyl chloride (dichlorophosphinyl) phenylhydrazone that is reacted with phenol to produce the desired benzoyl chloride phenylhydrazones. Certain of the compounds can be prepared by direct chlorination of a benzaldehyde phenylhydrazone. Methods of use and composition are described.
摘要:
Certain ( Alpha -fluoroalkyl)benzoyl chloride phenylhydrozones have been found to be anthelmintics and active against arthropod pests. The benzoyl ring and the phenylhydrazone ring can be otherwise substituted with, for example, halogen, nitro, another Alpha -fluoroalkyl group, or an alkyl group.
摘要:
Certain new benzoyl chloride (fluoroalkylphenyl)-hydrazones have been found to be active against arthropod pests and worms. The characterizing fluoroalkyl group on the phenylhydrazone ring can be associated with other substituent atoms and groups. The benzoyl ring can also be substituted. Representative substituent atoms and groups include the halogen atoms, lower-alkyl groups, lower-alkoxy groups, and a nitro group. The fluoroalkyl group is more meaningfully designated an '''' Alpha -Fnalkyl'''' group because fluorine atom substitution on the Alpha -carbon appears to be advantageous. The new compounds can be prepared by reacting a benzoic acid 2( Alpha -Fnalkylphenyl)hydrazide with phosphorus pentachloride to obtain a benzoyl chloride ((dichlorophosphinyl- Alpha Fnalkyl)phenyl)hydrazone that is reacted with phenol to produce the desired benzoyl chloride ( Alpha -Fnalkylphenyl)hydrazones. The compounds having chlorine on the phenylhydrazone ring can be prepared by direct halogenation of benzaldehyde ( Alpha Fnalkylphenyl)hydrazones or a benzoyl chloride ( Alpha Fnalkylphenyl)hydrazone. Methods of anti-arthropodal use and novel formulations adapted for biological use of the new compounds are also described.
摘要:
Certain new ar or ar'' (alkylthio) benzoyl chloride phenylhydrazones have been found to be anthelmintics and active against arthropod pests. The benzoyl ring and the phenylhydrazone ring can be otherwise substituted with, for example, halogen atoms, nitro groups, Alpha -fluoroalkyl groups, other alkylthio groups, and alkyl groups.
摘要:
Certain alkanoyl chloride phenylhydrazones have been found to be active against insects and mites, and also active as herbicides. The phenylhydrazone ring can be substituted. Suitable substituent groups are halogen atoms, the nitro group, the trifluoromethyl group, and alkyl groups of from 1 to 6 carbon atoms, inclusive. The compounds are prepared by reacting an alkanoic acid phenylhydrazide with phosphorus pentachloride to obtain an alkanoyl chloride (dichlorophosphinyl)phenylhydrazone intermediate that is reacted with phenol to produce the desired alkanoyl chloride phenylhydrazone. Certain compounds can be prepared by direct chlorination of an alkanaldehyde phenylhydrazone. Some of the compounds are novel. Methods of use and compositions are described.
摘要:
THIS INVENTION RELATES TO NOVEL HETEROCYCLIC ACID CHLORIDE PHENYLHYDRAZONES EMBRACED BY THE FORMULA
(R-CCL=N-NH-),(CL)N-BENZENE
WHEREIN R IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF FURYL, THIENYL AND PYRIDYL, EACH OF WHICH HAS FROM ZERO THROUGH THREE SUBSTUENTS SELECTED FROM THE GROUP CONSISTING OF ALKYL, HALO AND NITRO, AND N IS AN INTEGER OF FROM ZERO THROUGH THREE. THESE COMPOUNDS ARE PRIMARILY USEFUL AS INSECTICIDES AND MITICIDES AND ALSO AS HERBICIDES, ANTIINFLAMMATORIES AND ANTHELMINTICS.
