1H NMR chemical shifts and coupling constants of some 3-monosubstituted 2-methylpropenes

1H NMR chemical shifts and proton-proton coupling constants for some 3-substituted 2-methylpropenes [YCH2C(Me)CH2, Y = H, Cl, Br, I, OH, OMe, OEt, SH, SMe, SEt, NMe2 and NEt2] are reported. Resonances of the olefinic protons were assigned through lanthanide-induced shifts. Chemical shifts of the ole...

Resonances of the olefinic protons were assigned through lanthanide-induced shifts. Chemical shifts of the olefinic protons (HA and HB) showed a dependence on the substituent at C-3 of the allylic fragment. Long-range allylic coupling constants (4Jcisoid for HA and CH2 and HB and Me; 2Jtransoid for HB and CH2 and HA and Me) were determined by spectral expansion and simulation. © 1997 by John Wiley & Sons, Ltd.
