AbstractWe herein report the hydrogenation of substituted aryl‐ and heteroaryl boronate esters for the selective synthesis of cis‐substituted borylated cycloalkanes and saturated heterocycles. A cyclic (alkyl)(amino)carbene‐ligated rhodium complex with two dimethyl groups at the ortho‐alkyl scaffold of the carbene showed high reactivity in promoting the hydrogenation, thereby enabling the hydrogenation of (hetero)arenes with retention of the synthetically valuable boronate group. This process constitutes a clean, atom‐economic, as well as chemo‐ and stereoselective route for the generation of cis‐configured, diversely substituted borylated cycloalkanes and saturated heterocycles that are usually elusive and difficult to prepare.
