Evidence for the third isomer" Inorganic Chemistry 1977, 16, pp 415 - 421. A strained alkyne can be protected with dicobalt–octacarbonyl and we demonstrate for the first time that a strained alkyne can be re-formed and isolated under mild reaction conditions for further bioorthogon Sodium Amalgam (62% yield),20 again at room temperature and atmospheric pressure. Dicobalt octacarbonyl is the organometallic compound with composition Co2(CO)8. Due to its air sensitivity the monomer was directly used in a reductive olefination reaction with dicobalt octacarbonyl. In situ ATR-FTIR monitoring has allowed the direct study of the effect of additives (trioctylphosphine oxide [TOPO] and oleic acid) on the kinetics and rate of the thermal decomposition of dicobalt octacarbonyl leading to the formation of colloidal cobalt nanoparticles (CoCNPs). The treatment of 82 with dicobalt octacarbonyl furnished the desired hexacarbonyldicobalt complexed alkyne 83, which underwent an intermolecular Pauson–Khand cycloaddition in DCM to give the highly functionalized cyclopentenone 84 in good yield with high regioselectivity. This metal carbonyl is used as a reagent and catalyst in organometallic chemistry and organic synthesis, and is central to much known organocobalt chemistry. A protection–deprotection strategy for strained alkynes used for bioorthogonal chemistry is reported. Ensure adequate ventilation.
