Autor: H. McMurry, Conor N. O'Callaghan, T. Brian, John E. O'Brien

Publikováno v: Journal of Chemical Research. 2001:453-456

New N-isopropylidenehydrazinocarbonyl derivatives and other, related compounds display in solution two sets of characteristic NMR signals which are attributable to the presence of s-cis and s-trans conformers; the conformations are established by ext

Isomerisation of benzopyran-2-imines in [2H6]dimethyl sulfoxide

Autor: John E. O'Brien, Conor N. O'Callaghan, T. Brian H. McMurry

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :425-430

When 2-imino-2H-benzopyran-3-carboxamide 1 (X = H) is dissolved in [2H6]dimethyl sulfoxide, NMR spectra show that a mixture of 1 and the isomeric 2-cyano-3-(2-hydroxyphenyl)prop-2-ene-1-carboxamide 3 (X = H) is present. Other benzopyran-2-imines beha
