Allenylidene Phosphonium Ion: An Isoelectronic Phosphorus Analogue of [3]Cumulene

Angewandte Chemie International Edition, EarlyView.
We report the first isolobal and isoelectronic incorporation of a phosphorus atom into a [3]cumulene. This trigonal planar phosphonium allenylidene demonstrates exceptional Lewis acidity via a π* acceptor orbital and exhibits unique reactivity through a reversible intramolecular dearomative [2 + 2] cycloaddition reaction.

Scalable Main Group Mechanocatalytic CO2 Valorisation to Carbonate Species.

Angewandte Chemie International Edition, Accepted Article.
Over the past two decades, main group elements have gained attention as promising substitutes for precious metals in catalytic processes. Additionally, mechanochemistry is emerging as a field with the potential to promote catalytic reactions under mild conditions.
