Construction of a low-valent thiolate-bridged dicobalt platform and its reactivity toward hydrogen activation and evolution
文献摘要：
Low-valence transition metallic complexes have drawn longstanding attention due to their high reactivity toward catalytic transformation of various small molecules.Among these known complexes,the low-valence metal centres are commonly stabilized by neutral bulky ligands with strong electron-donating capacity.However,low-valence bimetallic complexes supported by anionic sulfur and cyclopentadienyl ligands are still difficult to obtain in high isolated yield.Herein,we report the synthesis and characteri-zation of two scarce thiolate-bridged CoⅠCoⅡ and CoⅠCoⅠ complexes bearing sterically demanding ligands through two stepwise one-electron reduction processes.Interestingly,the CoⅠCoⅡ complex can facilely promote the homolytic cleavage of dihydrogen across the short Co-Co metallic bond to give a CoⅡCoⅢdihydride bridged complex,which is capable of serving as a competent hydrogen atom transfer agent.Moreover,the anionic CoⅠCoⅠ complex can trigger a stepwise hydrogen generation cycle involving several isolated and structurally well-characterized intermediates.
