Abstract

A highly efficient oxidative carbonylation reaction of amines to ureas was developed making use of carbene–palladium complexes in the absence of any promoter. Both aliphatic amines and aromatic amines were transformed in good to excellent yields to the expected ureas.

## Abstract Hydrosilylation with well defined piano‐stool iron(II) complexes bearing both N‐heterocyclic carbene and cyclopentadienyl ligands was accomplished with both aldehydes and ketones. Typically, the reduction of aldehydes exhibited good activities (full reduction at 30 °C in 3 h), whereas f
