Notes:
15N Chemical shifts of N-nitroso-trans-decahydroquinoline, N-nitroso-cis-decahydroquinoline, of 12 methyl-or t-butyl-substituted N-nitrosodecahydroquinolines and of N-nitroso-trans-syn-trans-perhydroacridine are reported. Shift effects for N-nitrosation were calculated by comparison with the parent amines. Shift effects for ring substitution, obtained by comparison with the data of N-nitrosopiperidine, are of similar direction and magnitude as in the parent amines for the ring nitrogens (N-1). Methyl substitution nearly always causes deshielding for the nitroso nitrogens (N-2), with a very large deshielding if the planarity of the (C-α)2NNO region is disturbed.
