Hydrochlorination of 2,3-acetylenic acids with thionyl chloride in dimethylformamide

The reaction of 2,3-acetylenic acids (1a-d) with thionyl chloride in DMF under mild conditions gave E,Z-3-chloro-2-alkenoic acids (2a-d) or esters (3a-d) depending on treating the reaction mixture with either water or alcohols.

Nematicidal alkenanilides

A method is described for the control of nematodes in agricultural crops which comprises applying to the situs of infestation a nematicidal composition containing as active ingredient a compound of the formula STR1 wherein R1 and R2 are hydrogen, lower alkyl, or halogen, X is hydrogen or halogen, n is 1 or 2, Y is hydrogen, lower alkyl, halogen, trifluoromethyl, lower alkoxy, lower alkylthio, and nitro when n is 1, and halogen when n is 2, with the proviso that at least 1 of R1, R2, and X must be halogen. Preparation of active ingredient compounds is described, and nematicidal utility of compositions is exemplified.
