The Transition State in Acetolysis of Cyclohexyl Tosylate

Long-range carbon-13-proton coupling constants. I. Cyanopyridines

“…(ii) Vis normally in the range of [1][2][3][4] Hz; the coupling between 13C and the proton adjacent to nitrogen is remarkably enhanced to 8-9 Hz. (iii) V is not larger than 2 Hz.…”
