Hydro- and Chloroelementation Reactions Across an Iron–Carbon Bond Using Heavy Group 15 Reagents

Diaminostibines ({Sb}–H) react across the iron–carbon bond of a tucked-in iron diphosphine complex, resulting in hydrostibinated iron hydride [{Cp*-SbR2}Fe–H] complexes. Scope was broadened to include {Sb}–Cl and {Bi}–Cl chloroelementation reactions, providing new synthetic pathways to Sb- and Bi-containing heterometallics.
