Triallyl, trimethallyl and tripropargyl isocyanurates were synthesized in good yields by the reaction of the corresponding halides with potassium cyanate in dimethylformamide or dimethyl sulfoxide. Allyl and ethyl isocyanates were easily trimerized in the presence of alkaline salts in dimethylformamide. Tris (1, 3-pentadienyl) isocyanurate was synthesized by the trimerization of 1, 3-pentadienyl isocyanate in a saturated solution of sodium benzoate ...
