                                    Abstract13C NMR spectra (22.63 MHz) of 23 cyclic amine derivatives of N‐alkynylphthalimides, N,N′;‐dialkynylpyromellitic acid diimides, N‐alkynyloxyphthalimides and 5‐p‐chlorophenyl‐2‐(4‐t‐amino‐2‐butynyl)thio‐1,3,4‐thiadiazoles were analysed. The influence on the 13C chemical shift of oxygen insertion between the nitrogen of the phthalimides and the methylene group was summarized.
