Abstract

© 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim A borylidene–phosphorane, the lightest phosphoranylidene, which is stabilized by an N-heterocyclic carbene ligand, was synthesized and fully characterized. Experimental electron density analysis and DFT calculations indicate an enhanced ylene character (rather than an ylide character) with an exceptionally strong B→P π-back bonding related to the less electronegative boron compared to phosphorus.
