Abstract

The 53Cr nmr spectra of forty six chromium carbene complexes were recorded, and the chemical shift and line width data were discussed, along with associated infrared, UV-visible, and 13C spectroscopic data1. The 53Cr chemical shifts correlated very well with the donor-acceptor properties of the carbene ligand, and were quite sensitive to steric influences on efficiency of π-overlap of the heteroatom with the carbene carbon. No correlation was observed between the 53Cr chemical shift and the reactivity with imines to form β-lactams; however, the line width appeared to be related to reactivity. Preliminary attempts to utilize 53Cr nmr data to direct the synthetic utilization of chromium carbene complexes are reported.
