The first series of fully characterized homoleptic alkynyl bismuth compounds Bi(C≡CR)3 is presented. Facile homolytic Bi–C bond cleavage grants access to alkynyl radicals, which have been employed in...

Carbon monoxide (CO) is one of the simplest and most fundamental molecules that has fascinated chemists for decades. Early-on, chemists have recognized and exploited its favorable properties as a key ...

The simplistic methylbismuth dication has been captured only by the aid of monodentate tetrahydrofuran (thf) ligands, [BiMe(thf)5]2+. The hexacoordinate species shows a very unusual pentagonal pyrami...

Bismuth radical chemistry has attracted increased interest in recent years. Here, we report a series of bismuth–manganese complexes that catalyze the intramolecular redox-neutral coupling of alkyl iod...

Catalytic hydroboration of amides is highly important because the resultant amines are commonly found in natural products, pharmaceuticals, agrochemicals, dyes, and other applications. In comparison to the conventional reduction of amides using (over)stoichiometric reductants, hydroboration of amides using magnesium compounds represents a green and sustainable approach because magnesium is both Earth abundant and environmentally benign. However, there is only one report on magnesium-catalyzed deoxygenative hydroboration of secondary and tertiary amides. Here, we describe the synthesis and structural authentication of two new magnesium compounds (1 and 2) featuring a flexible PNP ligand and the utilization of 2 as a catalyst for the pinacolborane-mediated reduction of primary, secondary, and tertiary amides to amines. The reaction scope is explored, and a mechanism is proposed based on experimental and theoretical insights.

Compounds containing carbon–boron bonds serve as valuable intermediates for constructing more complex molecules by transforming these bonds into other carbon–element bonds. The catalytic dehydrogenati...

Well-defined cationic bismuth compounds have been exposed to simple α-olefins, including the benchmark substrate ethylene. Unprecedented and facile insertion, extrusion, and olefin exchange scenarios....

Fundamental bismuth compounds such as BiCl3 and BiBr(NMe2)2 form simple, colorful adducts with cyclic (alkyl)(amino)carbenes. They undergo facile and selective formal X+ and (NMe2)+ transfer from bis...
