A Hybrid Benzothiazolyl-NHC Ligand with a Flexible −CH2– Linker and Its Cationic Rh(I) Complex That Catalyzes the Olefin Hydrosilylation
A C,N-bidentate hybrid benzothiazolyl-NHC ligand (L) with a flexible −CH2– linker between the two moieties is devised. Classical deprotonation of the corresponding imidazolium bromide LHBr by M2O (M = Cu, Ag) affords the [(L)MBr] complexes 1 (M = Cu) and 2 (M = Ag), where the ligand L is monodentate by binding through the NHC only. A transmetalation with [Rh(COD)2]BF4 from both gives the cationic Rh(I) complex [(L)Rh(COD)]BF4 (3), which turns out to be a decent air-stable catalyst for olefin hydrosilylation giving anti-Markovnikov addition products under ambient benchtop conditions.
期刊介绍：
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
