Osmium(IV) Tetraaryl Complexes Formed from Prefunctionalized Ligands.

ABSTRACT: Transition metal(IV) tetraaryl, M(aryl)₄, complexes hold great promise as functional building blocks for complex organometallic materials, yet their widespread utility depends on the development of improved synthetic protocols and a deeper understanding of their chemical structure-property relationship(s). Here we show that Os(aryl)₄ complexes with preinstalled functional groups (-F, -Cl, -Br, -I, and -SMe) can be prepared from reactions between (Oct₄N)₂[OsBr₆] and Grignard reagents formed by halogen/magnesium insertion or exchange. This approach provides access to compounds that may otherwise prove challenging to prepare through postfunctionalization strategies, such as those comprising halogens in the 2- or 5-positions.
