Extended Synthetic Pathways Towards Dialkyl-Substituted Phosphanylboranes

open access: yesInorganics
Phosphine–boranes have garnered growing interest for their potential in catalysis and as building blocks for inorganic polymers. While various synthetic methods exist, flexibility to introduce diverse substituents on the P centers remains limited.

EDA Complex–Mediated C(sp3)–H Cross‐Dehydrogenative Coupling Enables Synthesis of Noncanonical α,β‐Diamino Acids

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Access to nonproteinogenic α,β‐diamino acids from simple feedstock precursors is of great interest to generate medicinal small molecule libraries. We report a regioselective photoinduced C(sp3)–C(sp3) cross‐dehydrogenative coupling (CDC) of N‐arylglycine derivatives with amides.

Alkali Metal Dihydropyridinates: From Hidden Intermediates to Promising Well-defined Catalysts?

open access: yesCHIMIA
Often the synthesis of catalysts can be time-consuming, multistep tasks, but sometimes they can turn up fortuitously, hidden treasure finds in essence. The alkali metal dihydropyridinate complexes discussed here fit the latter scenario.

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

Synthetic Implications of Spin States in the Reactivity of Ni Intermediate Complexes in Coupling Reactions

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The formation of triplet Ni(II) complexes by activation of bromoalkenes with alkyl‐ or boryl Ni(I) is key to control the outcome of the reductive cross‐coupling of bromoalkanes precluding the formation of alkylboronates. We present a mechanistic study on the Ni‐catalyzed cross‐coupling reaction of bromoalkanes with diboron compounds as reductants.

Is Li$_2$Pd$_3$B a self-doped hole superconductor ?

open access: yes, 2004
We propose that the electrons responsible for superconductivity in Li2Pd3B come from the palladium 4d-electrons. So, its electronic properties are likely to be dominated by strong electronic correlations.
