Based on ab initio calculated results, a new mechanism is proposed that intramolecular hydrogen atom transfer may occur Ž . during the photodissociation of o-chlorotoluene at 266 nm. This mechanism is different from the general suggestion, i.e. 1 Ž . Ž . Ž . Ž . o-chlorotoluene S TMo-chlorotoluene T TMClqo-tolylTMbenzylqCl. Our suggestion is 2 o-chlorotoluene S TMo1 1 1 Ž . Ž . Ž . chlorotoluen...

A D-A (donor-acceptor)-type chromophore may twist or flatten in its excited state to form a TICT (twisted intramolecular charge transfer) state or a PICT (planar intramolecular charge transfer) state, respectively. What is the driving force behind this twisting or planarization? Which geometry will occur for a certain D-A chromophore? To answer these questions, both fragment orbital interaction...

α,β-Unsaturated amidines can be synthesized in high yield by rhodium(II) carboxylate catalyzed 1,2-H shift following denitrogenation of α-diazo amidines. Using a large ligand and an electron-poor N-sulfonyl group results exclusive Z-selectivity excellent suppressing side reactions involving intramolecular oxygen transfer.
