While it is well known that chair forms of cyclohexane can interconvert without passing through the boat conformation, the same statement frequently comprises a source of confusion regarding the location of the boat conformation on the energy surface of the conformational inversion of cyclohexane. To alleviate this problem, a novel three-dimensional energy diagram has been introduced showing explicitly how the chair forms of cyclohexane interconvert through twist conformations along a first reaction coordinate that coincides with the x direction of a Cartesian system of coordinates, while simultaneously the twist conformations have the potential to interconvert through boat conformation transition states (pseudorotation) along a second reaction coordinate that coincides with the y direction of the same system of coordinates.

The anodic oxidation of EDTA was studied in acid sulfate solutions on platinized-Pt at 25~ Polarization relationships were obtained for the EDTA concentration range 3.42 • 10 -5 to 3.42 • 10-3M and pH range 0.35 to 3.80. Numerous reaction products were identified that indicated a sequential removal of acetate groups from the EDTA, each by an initial decarboxylation followed by a reverse Schiff-type reaction, that produced formaldehyde and the corresponding amine. A reaction sequence which correlated the experimental data involved Frumkin-type adsorption of the EDTA species through an unionized acetate group followed by a rate-determining electrochemical decarboxylation.Ethylenediaminetetraacetic acid, commonly abbreviated "EDTA," forms very stable, water-soluble complexes with many metal ions. Because of this, studies * Electrochemical Society Active Member.
