Formation of three- and two-electron σ-bonds by removal of lone pair electrons from a diamine
Abstract
8,9,10,11-Tetrahydro-7H-7,11-propanonaphtho-[1,8-bc][1,5]diazocine (1) is reversibly oxidised to (2) and (3); spectroscopic data for (2) and (3) suggest that simple two-centre 3- and 2-electron σ-bonds are formed in the oxidation.
