Hydro- and chloroelementation reactions across an iron–carbon bond using heavy group 15 reagents†

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