In the paper "Pi electron systems at high pressure" [Science 156, 1183 (1967)] a mechanism is suggested for the high-pressure reactions of perylene and azulene complexes with tetracyanoethylene (Figs. lOb and lOc) which is clearly impossible as drawn. What I had meant to suggest is the reaction shown below (with Fig. lOb as an example), which is at least conceivable, if not very probable from the chemical viewpoint. A similar modification would apply to Fig. lOc.

As indicated in the paper, any serious study of the reaction requires the synthesis of enough product for more complete analysis, as well as a fairly detailed knowledge of the crystal geometry of the unreacted complex.
