Hydroboration of internal alkynes catalyzed by FeH(CO)(NO)(PPh<sub>3</sub>)<sub>2</sub>: a case of boron-source controlled regioselectivity
Fabian Rami, Franziska Bächtle, Bernd Plietker
Abstract
The Fe–H complex FeH(CO)(NO)(Ph<sub>3</sub>P)<sub>2</sub> catalyzes the stereoselective, regiodivergent hydroboration of internal alkynes using either pinacolborane (HBpin) or bis(pinacolato)diboron (B<sub>2</sub>pin<sub>2</sub>) as a boron source.
