1D Coordination Polymer Derived from Redox‐Active Digallane

Abstract

The reaction of [LGa−GaL] (1) (L=dpp‐bian=1,2‐bis[(2,6‐diisopropylphenyl)imino]acenaphthene) with 4,4′‐bipyridine (4,4‐bipy) results in the formation of complex [L2(4,4‐bipy)2Ga2] (2). The reaction of 1 with 1,3‐bis(4‐pyridyl)propane (1,3‐Py2(CH2)3) affords 1D coordination polymer [L2(μ2‐1,3‐Py2(CH2)3)Ga2]n (3). Compounds 2 and 3 were characterized by 1H NMR and IR spectroscopy; their molecular structures were established by single‐crystal X‐ray analysis.

Diversity of transformation of heteroallenes on acenaphthene-1,2-diimine aluminum oxide

“…29,34,35 For instance, the addition of an excess of CO 2 to aluminum oxide 1 leads to the formation of carbonate [(dpp-bian)Al(μ-O) (μ-CO 3 )Al(dpp-bian)]. 19 Reactions of 1 with an excess of phenyl-and cyclohexylisocyanates proceed in the same manner. During the reaction the isocyanate inserts into only one Al-O bond of oxide 1 regardless of the reactants ratio (Scheme 1).…”

“…[30][31][32] For a deeper understanding of the reactivity of compounds with Al-O bonds, we have continued the study of oxide [(dpp-bian)Al(μ 2 -O) 2 Al(dpp-bian)] (1). 19 Here we report the reactivity of compound 1 towards carbodiimides and isocyanates, as well as its catalytic activity in hydroboration reactions.…”

“…[14][15][16][17] Most of the alumoxanes stabilized by bulky ligands are dimeric molecules with one or two oxobridges. 8,18,19 There are also rarer examples of compounds with a double AlvO bond [20][21][22] (Fig. 1).…”

Reduction of Nitrous Oxide and Binding of Carbon Dioxide by Acenaphthene-1,2-diimine Aluminum Compounds

“…Interestingly, digallane [(dpp-bian)Ga−Ga(dppbian)] easily reacts with N 2 O in toluene in the presence of pyridine to afford the gallium oxide analogous to 4. 33 The diamagnetic 4 was characterized by NMR and IR spectroscopy. Its molecular structure has been determined by the single crystal X-ray analysis.…”

Coordination polymers derived from alkali metal complexes of redox-active ligands

“…36,37 So far, only a few coordination polymers derived from dpp-bian and the related tetrakis(imino)pyracene (TIP) ligand have been reported. [38][39][40] While dpp-bian acts as a terminal ligand in coordination polymers of calcium, strontium and gallium, 39,40 the TIP ligand serves as a bridging one in complex with Cu 2 Br 2 . 38 To build-up coordination polymers of alkali metal salts of the dpp-bian radical-anion, (dpp-bian) 1− M 1+ (M = Li, Na, K), we have chosen 4,4′-bipyridine (4,4′-bipy) to act as a linker.…”
