Abstract:A new
series of O∧C-chelate tetra-coordinated boranes with
naphtha-aldehyde as the chelate backbone have been synthesized. Their
photophysical and photochemical properties have been examined, which
show that all of the compounds can undergo both photo and thermal
transformations, generating aryl-migrated [1,2]oxaborinine derivatives
as the major products. 1,3-Sigmatropic shifts and an intramolecular
nucleophilic addition mechanism are proposed for the photochemical
and thermal conversion pathways, respectively. Show more
