Reaction of (Z)- and (E)-beta-chlorocinnamohydroximoyl chlorides with methoxide ion

New alpha,beta-unsaturated hydroximoyl chlorides and hydroximates were synthesized and characterized. 13C NMR, 1H NMR, IR and elemental analysis were determined for each new compound. The kinetics of methoxide ion substitution on (Z)- and (E)-beta-chlorocinnamohydroximoyl chloride were measured. Identification of the products and the measurement of the rate constants helped with an understanding of the mechanisms of these reactions.
