As a proof-ofprinciple, the electrocyclic ring-expansion of a benzazirine to a ketenimine was induced, in a cryogenic matrix, by near-IR light tuned at the overtone stretching frequency of its OH remote antenna. This accomplishment paves the way for harnessing IR vibrational excitation as a tool to guide a variety of molecular structure manipulations in an exceptional highly-selective manner. | URI: | https://hdl.handle.net/10316/107465 | ISSN: | 1359-7345 1364-548X |
