April 2000Abstract: Thermolysis of semicarbazones (I) to azines (II) occurs through reactive N-substi-tuted isocyanate intermediates (Ia) which can be converted in situ to carbamates and N-substituted ureas.Keywords: Thermolysis, Semicarbazones, Azines, N-substituted isocyanates, Mesogeniccompounds.IntroductionThe isocyanate group is one of the most important synthons and intermediates in Organic Chemistry[1]
