Substituent Effects on 1H Chemical Shifts I-Complete 1H Chemical Shift Assignments of Methyl-Substituted Cyclic Systems

Article abstract of DOI:10.1002/mrc.1260300412

1H chemical shift assignments are presented for 2-methyladamantane, 2-methylnorbornane (endo and exo) and 2-methylnorbornene (endo and exo).Resonance assignment was achieved using a variety of 1D and 2D homo- and heteronuclear (1H-13C)experiments.The methyl group-induced substituent chemical shift (SCS) is derived and the SCS of protons vicinal to this group is discussed.KEY WORDS Norbornanes Norbornenes Adamantanes 1H NMR Substituent chemical shifts
