Tris(bicyclo[1.1.1]pentyl)phosphine can be prepared by radical addition of PH3 to [1.1.1]propellane, giving the smallest tri-tert-alkylphosphine known. PBcp3 is substantially smaller than PCy3 and comparable in electron-donating power PEt3. It gives a bis-ligated Pd(0) complex Pd(PBcp3)2 that exceptionally reactive toward alkyl halide oxidative functions as general ligand for palladium-catalyzed cross-coupling sp3 electrophiles. Radical [1.1.1]propellane phenylphosphine bis(bicyclo[1.1.1]pentyl)phosphine derivative PBcp2Ph, illustrating generality this approach bicyclopentylphosphine synthesis.

Abstract Controlling the metal geometric and electronic structure is of significance in developing efficient catalysts for heterogeneous hydroformylation. This study examines structural sizes Rh + ‐Rh 0 distribution to construct a highly active catalyst formaldehyde The sites hydroformylation require several n atoms, while single‐atom can solely catalyze hydrogenation. highest activity was achieved on nanoclusters (0.95 nm), giving TOF 191 h −1 selectivity 82% glycolaldehyde formation. tunability properties synergistic interaction between are essential enhanced activity. Pseudo‐ situ FT‐IR analysis elucidated that adsorbed nanocluster prefers produce via hydroformylation, isolated δ+ tends form methanol provides new insight into design guidance understanding reaction mechanism aldehydes/olefins
