Abstract
The reaction of aluminum bis-formate acenaphthene-1,2-diimine complex [(ArBIG-bian)Al(μ-OC(H)O)2Li(Thf)2] (I) (ArBIG-bian = 1,2-bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene), prepared by binding carbon dioxide by aluminum diimine hydride [(ArBIG-bian)Al(H)2]–[Li(Thf)4]+, with borane dimethyl sulfide and ammonia was studied. The reaction of I with BH3∙SMe2 (1 : 1) in toluene affords the product of hydroboration of one formate group [(ArBIG-bian)Al(μ-OC(H)O)(OB(H)OCH3)Li(Thf)]2 (II), while the reaction of I with BH3∙SMe2 (1 : 2) is accompanied by reduction of both formate groups and gives complex [(ArBIG-bian)Al(OBOCH3)2OLi2(Thf)2BH4]2 (III), methoxyboroxine (CH3OBO)3 and, presumably, compound [(ArBIG-bian)AlOCH3]. The reaction of I with one equivalent of ammonia in THF gives adduct [(ArBIG-bian)Al(NH3)(μ-OC(H)O)2Li(Thf)2] (IV), in which ammonia is coordinated to the aluminum atom, while the key bonds in I have not undergone ammonolysis. Compounds II–IV were characterized by IR and NMR spectroscopy, elemental analysis, and X-ray diffraction (CCDC no. 2255017 (II), 2255018 (III), 2255019 (IV)).
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
