Metal-only Lewis pairs (MOLPs) based on zinc electrophiles are particularly interesting due to their relevance to Negishi cross-coupling reactions. Zinc-based ligands in bimetallic complexes also render unique reactivity to the transition metals at which
Oxidative ring expansion of a low-coordinate palladacycle: Synthesis of a robust T-shaped alkylpalladium(II) complex

The synthesis of an unusual T-shaped alkylpalladium(II) complex featuring a cyclometalated tri-tert-butylphosphineoxide ligand by oxidation of the corresponding cyclometalated tri-tert-butylphosphine complex with PhIO is reported. We speculate that this reaction proceeds by formation of a transient palladium oxo intermediate and there are structural similarities with a late transition metal exemplar: Milstein's seminal pincer ligated Pt(IV) oxo (Nature 2008, 455, 1093–1096).

A tert-butyl Grignard reagent is reacted with phosphorus trihalide and boron trifluoride, the reaction is finished, a hydrofluoric acid aqueous solution is added to form a salt, the layering is extracted, and the tri-tert-butylphosphonium - tetrafluoroborate is obtained through recrystallization. The method is simple, feasible, safe and environment-friendly. When the tert-butyl Grignard reagent is reacted with the phosphorus trihalide, the tert-butyl phosphorus intermediate acts in the reaction process by adding the boron trifluoride complex, thereby improving the halogen ion release property, improving the tri-substituted product to 94 - 95%, the reaction yield 85 - 87% and the organic solvent can be recycled.
