[Cp*RhCl2]2: mechanosynthesis and applications in C–H bond functionalisations under ball-milling conditions†
Abstract
A mechanochemical synthesis of [Cp*RhCl2]2 has been developed. Under LAG conditions the organometallic complex can be prepared in a shorter reaction time compared to the standard solution-based protocol. The obtained Rh(III) dimer is then applicable as catalyst in subsequent solvent-free mechanochemical C–H bond functionalisations of 2-phenylpyridine.
