Stable α-NHC-boryl carbonyl compounds (NHC-BH2-CHRCOR′) are isolated in good yields. The reaction is a reliable way to make boron-carbon bonds with good tolerance for variation in both the NHC-borane and diazocarbonyl components. It presumably occurs by insertion of a transient rhodium carbene into a boron-hydrogen bond of the NHC-borane. Competitive experiments show that a typical NHC-borane is highly reactive toward rhodium carbenes. © 2013 American Chemical Society. date: 2013-08-14 type: Article type: PeerReviewed format: text/plain language: en rights: attached identifier: http://d-scholarship-dev.library.pitt.edu/27585/1/licence.txt identifier: Li, X and Curran, DP (2013) Insertion of reactive rhodium carbenes into boron-hydrogen bonds of stable N-heterocyclic carbene boranes.
