Imidoyl phenyl selenides have been shown to be precursors to phenanthridines, when treated with Pd(PPh 3 ) 4 under reflux in toluene in the presence of a base, giving reasonable yields. It is proposed that insertion of palladium into the C-Se bond is followed by cyclisation onto a phenyl ring and subsequent aromatisation by elimination of HPdSePh.
