Structure and protonation of the bis-ethylene adduct [Pt(micro-PBut2)(eta2-CH2=CH2)]2. Pt-H-P agostic interaction and proton scrambling.
The bis-ethylene derivative [Pt(micro-PBu(t)(2))(eta(2)-CH(2)=CH(2))](2) was prepared and characterized by X-ray diffraction; its protonation affords [Pt(2)(micro-PBu(t)(2))(micro-PBu(t)(2)H)(eta(2)-CH(2)=CH(2))(2)](CF(3)SO(3)), with a rarely observed P-H-M agostic proton in rapid exchange with those of the adjacent ethylene molecule.
