Synthesis and characterization of new tetraalkylaminophosphonium chlorides

Dinuclear Palladium(II) and Platinum(II) Complexes of a Readily Accessible Bicyclic Diphosphane

“…A tentative mechanism [17] to account for this rearrangement leading to P − P(NMe 2 ) is shown in Scheme 2 [Ar=−C 6 H 4 (4‐NMe 2 ]. Upon initial formation of a tetralkylphosphonium salt A , [16b] we were able to observe the intermediate tertiary phosphine B by 31 P NMR spectroscopy [δ(P) −40 ppm] [16a,23] . Collapse of B , via P−C cleavage/PR 2 radical coupling reactions affords the speculated acyclic species C .…”
