WebApr 12, 2024 · The steric tuning of a tridentate acridane-derived NNN pincer ligand allows for the isolation of a strictly T-shaped phosphine that exhibits ambiphilic reactivity. Well-defined phosphorus-centered reactivity towards nucleophiles and electrophiles is reported, contrasting with prior reports on this class of compounds. WebPrimary phosphines can add to carbon–carbon (or other unsaturated double bonds) under a variety of conditions to give new phosphorus (III) compounds.41 Furthermore, another reaction of primary (and secondary) phosphines is their ready conversion into air-stable, crystalline hydroxymethylphosphonium salts by reaction with an excess of formaldehyde … how does filipino greet
