摘要：

Synthesis and Coordination Ability of Selenoalkynes R ‐ Se ‐ C ≡ C ‐ R′ Several synthetic methods for the preparation of selenoalkynes R–Se–C≡C–R′ (1) are discussed. 1 reacts with octacarbonyl dicobalt to yield the η2‐π‐side‐on coordinated alkyne complexes R‐Se[(η2‐C≡C–R′)Co2(CO)6 (8) which contain a sterically hindered carbon–cobalt tetrahedrane cluster unit. The identity of compounds 1 and 8 is documented by analytical and spectroscopic [IR, MS, 1H‐, 77Se‐, and 13C‐NMR) data as well as by X‐ray analysis of C6H5)Co2‐(CO)6] (8a).
