Synthesis and reactions of [(OC)3Fe(µ-dppm)(µ-CO)Pt(PPh3)] with acetylenes or allene: crystal structures of [(OC)3Fe(µ-dppm)(µ-CO)Pt(PPh3)], [(OC)2Fe(µ-dppm){µ-σ:η3-C(O)C2H2}Pt(PPh3)], and [(OC)3Fe(µ-dppm){µ-CH2C(CH2)}Pt(PPh3)](dppm = Ph2PCH2PPh2)

Abstract

[(OC)₃Fe(µ-dppm)(µ-CO)PtCl₂](dppm = Ph₂PCH₂PPh₂) is reduced by NaBH₄ in the presence of PPh₃ to give the electron-rich [(OC)₃Fe(µ-dppm)(µ-CO)Pt(PPh₃)], which reacts with acetylene(s) or allene under mild conditions to give the title compounds and is protonated to give a hydride.
