effect for the Z and E isomers are kZBr/kZCl = 3.08 and kEBr/kECl = 2.38. The Z-to-E rate ratios are 0.25 (chlorides) and 0.33 (bromides). These reactions are proceeding by rate-determining nucleophilicattack by the alkoxide ion on the carbon–nitrogen double bond (AN# + DN). The restricted stereochemistry of the tetrahedral intermediates suggests that the E-hydroximoyl bromide and chloride may be
