“…However, the formulation of the 3-pyrroline dithiocarbamate complex [Ni(S 2 CNC 4 H 6 ) 2 ] ( 12 ), shown in Scheme , was supported by elemental analysis. Although the [S 2 CNC 4 H 6 ] − ligand has been prepared before, it has found most use in main-group compounds such as [O(SiMe 2 CH 2 ) 2 TeI(S 2 CNC 4 H 6 )] . The 1 H NMR data for this compound consist of a broadened singlet at 4.50 ppm and a singlet at 5.92 ppm, values which are in good agreement with those observed for 12 .…”

“…The 1 H NMR data for this compound consist of a broadened singlet at 4.50 ppm and a singlet at 5.92 ppm, values which are in good agreement with those observed for 12 . As a further means to confirm the formulation, 12 was prepared through a different route, by direct reaction of Ni(OAc) 2 with an excess of preformed KS 2 CNC 4 H 6 . Identical data were recorded for the compounds prepared by this alternative route.…”

The complex cis-[RuCl 2 (dppm) 2 ] reacts with the diallyldithiocarbamate KS 2 CN(CH 2 CHdCH 2 ) 2 to form [Ru{S 2 CN(CH 2 CHdCH 2 ) 2 }(dppm) 2 ] þ . The same ligand was also used to prepare the alkenyl complexesferrocene) were prepared from the respective precursors [MCl 2 (L 2 )] (L 2 = dppp, dppf) and KS 2 CN(CH 2 CHdCH 2 ) 2 in the presence of NH 4 PF 6 . In a similar manner, treatment of the cyclometalated dimer [Pd(C,N-CH 2 C 6 H 4 NMe 2 )Cl] 2 with the dithiocarbamate ligand yielded [Pd(C,N-CH 2 C 6 H 4 NMe 2 ){S 2 CN(CH 2 CHdCH 2 ) 2 }]. The homoleptic literature complexes [Ni{S 2 CN(CH 2 CHdCH 2 ) 2 } 2 ] and [Co{S 2 CN(CH 2 CHdCH 2 ) 2 } 3 ] were also prepared and characterized. Ring-closing metathesis catalyzed by [Ru(dCHPh)Cl 2and [Ru(CHdCHC 6 -H 4 Me-4)(S 2 CNC 4 H 6 )(CO)(PPh 3 ) 2 ], respectively. These complexes were also directly prepared from the reaction of the appropriate starting materials with preformed KS 2 CNC 4 H 6 . The more sterically crowded complex [Co{S 2 CN(CH 2 CHdCH 2 ) 2 } 3 ] failed to give a reaction with the metathesis catalyst, although it could be prepared directly from KS 2 CNC 4 H 6 and cobalt acetate. The compounds [Ru(CHdCHC 6 -H 4 Me-4){S 2 CN(CH 2 CHdCH 2 ) 2 }(CO)(PPh 3 ) 2 ], [Ni{S 2 CN(CH 2 CHdCH 2 ) 2 }(dppp)]PF 6 , and [Ni(S 2 -CNC 4 H 6 )(dppp)]PF 6 were characterized crystallographically.

“…Such type of shift has been observed in similar compounds [11]. However, these data contrast with the downfield shift observed for the compound O[Si(CH 3 ) 2 CH 2 ] 2 TeS 2 CNR 2 [12], which is in agreement with that of compound 4 (695 ppm) showing a downfield shift with regard to the diiodo-tellurocycles.…”

This chapter gives a systematic account of and surveys the available data on 77 Se and 125 Te NMR spectra of organochalcogen compounds such as chacogenols, mono and dichalcogenides, chalcogenolates, tetra and hexa substituted chalcogen compounds, chalcogenyl halides, chalcogen‐containing heterocycles and macrocycles, chalcogen‐oxygen/nitrogen compounds, etc. The review is based on the literature from 1985 to 2011 and includes 780 references. The 77 Se/ 125 Te NMR spectra of organochalcogen compounds reveal expansive chemical shifts (δ Se /δ Te ) leading to sharp sensitivity of these nuclei (Se/Te) to their environment such as solvent, temperature, molecular geometry, ligand backbone, oxidation state, chelate ring size, steric strain, etc. This is well illustrated by the advantageous use of this spectroscopy in the successful determination of the solution state structure of several organochalcogen compounds. It is noted that the 125 Te and 77 Se chemical shifts of a large number of structurally similar organotellurium and selenium compounds show linear relationship.
