Carbon-13 nuclear magnetic resonance study of coordinated thiocyanate, selenocyanate, and cyanate

Pseudohalide complexes of palladium(II) containing PCP pincer: Synthesis, characterization, and their antimicrobial activities

“…The resonance signal is slightly shielded as compared to that of the free NCO anion at d 131.1 (NaNCO in D 2 O in a sealed capillary), also supporting the N-coordination of the isocyanate ligand in 3. This observation is consistent with the previous report demonstrating that the 13 C resonance signals of the isocyanate ligands upon coordination through nitrogen (MeNCO) shift to upfield, slightly, as compared to that of the free NCO anion [78].…”

Architecture of a new selenocyanato bridged one-dimensional polymeric complex of cadmium(II): synthesis, crystal structure and spectroscopic studies

“…Signals at 119 ppm for selenocyanato carbon represent its N-bonded coordination. All the 13 C shifts are consistent with results for complex 1 for the observed mode of bonding in a number of inorganic and organic complexes [29][30][31].…”

Synthesis of trifluoromethylated heterocycles using partially fluorinated epoxides

“…2140 cm À1 for alkyl thiocyanates [20]) and 13 C NMR, spectroscopy (7, -S-CN, d = 110.16 ppm, cf. d = 112.1 and 127.8 ppm for C 2 H 5 SCN and C 2 H 5 NCS, respectively [21,22]). Interestingly, compound 7 has significantly higher stability compared to compound 5.…”

“…However, when the reaction of 2 and phenyl isothiocyanate (22) was carried out in the presence of tetrabutylammonium fluoride catalyst, it resulted in high yield formation of imine 22a (Scheme 13).…”
