摘要

The reaction of (dpp-bian) AlEt(Et2O) (1) (dpp-bian = 1,2-bis[(2,6-diisopropylphenyl) imino] acenaphthene) with 4,4'-dimethoxybenzophenone leads to the replacement of Et2O with the ketone resulting complex (dpp-bian)AlEt[O=C(4-MeOC6H4)(2)] (2). The reaction of compound 1 with 2,6-di-tert-butyl-4-methylphenol (1 : 1) or Ph2NH (1 : 1) affords the addition products [dpp-bian(H)]AlEt[O(2,6-tBu(2)-4-MeC6H2)] (3) and [dpp-bian(H)]AlEt(NPh2) (4) correspondingly. Treatment of complex 1 with 0.5 molar equivalents of H2O gives ethylalumoxane {[dpp-bian(H)]AlEt}(2)(mu-O) (5). Newly prepared complexes 2-5 have been characterized by NMR and IR spectroscopy, and the molecular structures of 2, 3, and 5 have been determined by single crystal X-ray analysis.

Alkali Metal Reduction of 1,2-Bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene (ArBIG-bian) to Radical-Anion

Mikhail V. Moskalev, Danila A. Razborov, Alexandra A. Skatova, Andrey A. Bazanov, Igor L. Fedushkin

Summary: The reduction of Ar-BIG-bian with Li, Na, or K in THF yields radical-anionic salts, which were characterized and found to prevent dimerization of the complexes. Coordination of bulky Ph-2(H)C groups in the ligand with alkali metals results in a saturated coordination sphere.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
