Abstract

Proton, carbon-13, nitrogen-15, fluorine-19, and silicon-29 NMR chemical shifts and coupling constants are reported for nine N-substituted anilines of the type XC6H4N(H)Y, where X H and F, and Y Si(CH3)3, Ge(CH3)3, Sn(CH3)3, and P(BH3)(CH3)2, and the 15N isotopomer of N-trimethylsilylaniline. Resonances in the natural-abundance carbon-13 NMR spectra for both sets of derivatives are assigned on the basis of additivity relationships, proton-coupled spectra, and relative magnitudes of |J(31P13C)| and |J(19F13C)| coupling constants where appropriate. Carbon-13 and fluorine-19 chemical shifts, and |1J(13C1H)| coupling constants indicate that the P(BH3)(CH3)2 group is substantially electron-withdrawing. © 1992.
