Notes: 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).
