Synthesis and characterization of α,β-unsaturated hydroximoyl chlorides and hydroximates
New α,β-unsaturated hydroximoyl chlorides (PhC(Cl)≤CHC(Cl) ≤NOCH3) and hydroximates (PhC(OCH3)≤CHC(OCH 3)≤NOCH3) were prepared. The ZZ-isomer of PhC(Cl)≤CHC(Cl)≤NOCH3 was prepared in four steps from e

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.
