Abstract
A novel and air-stable organo(hydro)diborane featuring a five-membered aryl ring supported bridging B-C-B three-centre-two-electron (3c-2e) bond has been reported. Pyrido[1,2-a]isoindole was found to undergo a stepwise BH3addition reaction, during which a mono-BH3adduct was formed from a electrophilic addition at the Cγin pyrido[1,2-a]isoindole. A molecule of hydrogen was eliminated throughout the second step of addition reaction. DFT calculations indicate that the H2evolution is concerted to the second BH3addition rather than forming B-C before the second BH3attack.
