Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, Volume 29, Issue 38, 13 October 2026.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...

An Iridium Distannylidyne – Expanding the Scope of Tetrylidyne Transition Metal Coordination Chemistry

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
This work presents the synthesis, characterization, and reactivity of an iridium distannylidyne as the first heavy transition metal ditetrylidyne. Characterized by its short Ir─Sn bonds and linear bonding angles at the tin atoms, this compound displays versatile reactivity toward carbon dioxide and trimethylsilyl azide.

Reactions of Terminal Olefins With Iron Carbenes

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Iron carbenes react with terminal olefins and show productive metathesis or metathesis‐divergent pathways depending on the nature of the olefin. Reactions proceed through 2π + 2π cycloadditions to generate transient metallacyclobutane intermediates that undergo cycloreversion to generate the metathesis product or the metathesis‐divergent β‐hydride ...
