The nature of solid-state N-H triplebondO/O-H triplebond N tautomeric competition in resonant systems. Intramolecular proton transfer in low-barrier hydrogen bonds formed by the triplebond O=C-C=N-NH triple bond --> <-- triplebond HO-C=C-N=N triplebond Ketohydrazone-Azoenol system. A variable-temperature X-ray crystallographic and DFT computational study.
Gilli P, Bertolasi V, Pretto L, Lycka A, Gilli G. Gilli P, et al. Among authors: gilli g. J Am Chem Soc. 2002 Nov 13;124(45):13554-67. doi: 10.1021/ja020589x. J Am Chem Soc. 2002. PMID: 12418911
The problem of the N-H triplebond O/O-H triplebond N competition in these compounds is studied here through variable-temperature (100, 150, 200, and 295 K) crystal-structure determination of pF = 1-(4-F-phenylazo)2-naphthol and oF = 1-(2-F-phenylazo)2-naphthol, two molecules that …
