Serial title, monograph or event: | Chemical Communications | Volume: | 57 | Issue: | 75 | Abstract: | We demonstrate here that selective vibrational excitation of a moiety, remotely attached in relation to the molecular reaction site, might offer a generalized strategy for inducing bond-breaking/bond-forming reactions with exquisite precision. As a proof-of-principle, 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/10316/101244 | DOI: | 10.1039/d1cc03574f | Rights: | embargoedAccess |
