Abstract

Dialumane 1 reacts with tBuNC to produce a reductive dimerization adduct [LAl(tBuN[double bond, length as m-dash]C-C[double bond, length as m-dash]NtBu)AlL] (2). In the presence of Na, 1 can promote linear- and cyclo-trimerization of isocyanides, affording products [Na][LAl{(tBuNC)3}AlL] (3 and 4) and [Na][LAl{(tBuNC)3}Al(C[triple bond, length as m-dash]N)L] (5), the latter of which features a unique aromatic tri(tert-butylimino)deltate dianion [C3N3(tBu)3]2-.

Abstract

The direct oxidative synthesis of α-ketoamides via anodic oxidation was developed by using dioxygen as a reactant under mild conditions. This methodology has a broad substrate scope (aromatic amines, aliphatic amines and ammonium acetate) and opens up an interesting and attractive avenue for the synthesis of α-ketoamide derivatives.

Abstract

Truncated acetyl-coenzyme A synthase (ACS) was successfully converted into functional nickel superoxide dismutase (Ni-SOD) by molecular design and the designed metalloproteins possess new spectroscopic, structural, and electrochemical characteristics required for catalyzing O(2)(˙-) disproportionation, and exhibit impressive Ni-SOD activity.

Abstract

Direct electrochemical synthesis of sulfonyl amidines from aliphatic amines and sulfonyl azides was realized with good to excellent yields. Traditional tertiary amine substrates were broadened to secondary and primary amines. The reaction intermediates were observed and a reaction mechanism was proposed and discussed.
