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*-SbR}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.
