The chemical reactivity of some benzylidenemalonocarbonyls with a nucleophile, 2-diethylaminoethyl mercaptan, is evaluated. Polarographic half-wave potentials E12 and chemical rate constants k1 of 20 compounds are used to establish the correlations. Diethyl benzylidenemalonates, ethyl benzylideneacetoacetates, 3-benzylidene-2,4-pentanediones, and benzylidenemalonamides give linear relationships of E12 and 1n k1. The first three series are linearly intercorrelated while the remaining one is not. The difference could be due to an alteration in the electrode process of the benzylidenemalonamide series. Author
