A series of novel sulfide derivatives containing 1,3,4-oxadiazole and pyridine were synthesized, characterized, and tested for their antibacterial activity against tobacco bacterial wilt and rice bacterial blight and for insecticidal activity toward diamondback moth. The results showed that some compounds had good insecticidal and bactericidal activity, e.g., the activities of compounds 6e and 6g–6j toward tobacco bacterial wilt were much better than those of commercial thiodiazole-copper, and some of the synthesized compounds possessed good insecticidal activity against Plutella xylostella. Compounds 6d, 6h, 6j, 6l, 6p, 6r, and 6p displayed over 93% activity at 500 mg L? 1.
Method for preparing aromatic compounds
-
, (2008/06/13)
A method for synthesizing aromatic compounds by selectively dehalogenating aromatic starting materials is provided. Compounds may be prepared which are substituted with fluoro, chloro or bromo. The method may be used to remove halogen atoms from sites at which halogenation is not desired, and to form substantially pure halogenated compounds from mixtures of starting materials. The method uses a copper containing dehalogenation agent and an acid with the dehalogenation being controlled by a substituent such as a carboxylic acid, amide, ester, aldehyde, ketone or cyano on the aromatic ring.
