Synthesis and structures of gold(I) phosphine complexes containing monoanionic selenocarbamate ester ligands

Old Selenium Heterocycles Revisited: Synthesis, Spectroscopic, and Structural Characterization ofN‐Acyl‐1,3‐selenazol‐2(3H)‐imines and 5‐Acyl‐1,3‐selenazol‐2‐amines from Acylselenourea Derivatives

“…Given that there are published reports of incorrectly assigned structures of chalcogen‐containing heterocycles formed by reactions of chalcogenoureas with phenacyl bromides, we wished to reexamine the reactions reported by Liebscher and Hartmann and to spectroscopically and structurally characterize the products to allow unambiguous assignment of the structures. This study also represents a continuation of our work on the coordination chemistry of selenoureas and other organoselenium compounds …”

Acylselenoureas, selenosemicarbazones and selenocarbamate esters: Versatile ligands in coordination chemistry

“…139 Our group has reported the preparation and crystal structures of various mono-and dinuclear gold(I) phosphine complexes containing the deprotonated selenocarbamate ester [PhNC(Se)OMe] -, which coordinates to gold only via selenium (Scheme 10). 140,141 Scheme 10…”

Silver and gold

“…165 Gold(I) phosphine complexes containing monoanionic, Se-coordinated selenoamide ligands were formed by the reaction of N-phenyl-O-methylselenocarbamate with [AuCl(P)] (P = phosphine ligand) in the presence of base. 166 Thiophene functionalised thiosemicarbazone ligands display two different binding modes in silver(I) phosphine complexes: In one case, the neutral thiosemicarbazones act as bridging ligands between two silver atoms, whilst in halide bridged Ag 2 complexes they act as terminal ligands. 167 Mono-and di-nuclear silver(I) phosphine complexes containing the multidentate 4-amino-3-thioxo-3,4-dihydro-1,2,4-triazin-5(2H)-one ligands were reported.…”
