N,N'-Dialkylcyclohexane-1,2-diimines react with trivalent phosphorus acid chlorides to give, depending on the structure of the organophosphorus reagent and reaction conditions, either 1,3,2-diazaphospholanes (three-coordinate phosphorus) containing the cyclohexadiene fragment in positions 4 and 5, or 1,3,2-diazaphospholines (four-coordinate phosphorus).
