摘要：

The reactions of [(ArBIG-bian)Al(H)2Li(THF)4] (1) (ArBIG-bian = 1,2-bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene, THF = tetrahydrofuran), [(dpp-bian)Al(H)2Li(THF)3] (2) (dpp-bian = 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) and [(dpp-bian)AlH(Cl)][Na(DME)3] (3) (DME = 1,2-dimethoxyethane) with carbon dioxide proceed with its insertion into Al–H bonds and afford [(ArBIG-bian)Al{μ-OC(H)O}2Li(THF)2] (4), [{(dpp-bian)AlOC(H)OLi(THF)3}2μ-O] (5) and [(dpp-bian)Al(µ-O){µ-OC(H)O}Al(dpp-bian)][Na(DME)3] (6) respectively. Complex 5 is a product of thermally induced transformation of bis-formate intermediate [(dpp-bian)Al{μ-OC(H)O}2Li(THF)n] (5a), which can be isolated from the reaction of 2 and CO2 at ambient temperature. Newly prepared compounds were characterized by IR and NMR spectroscopy; molecular structures of products 4, 5 and 6 were established by single-crystal X-ray analysis. © 2021
