Reactions of Heteroaryliminotriphenylphosphoranes with Heterocumulenes: Synthesis and Cycloaddition Reactions of α-N-Heteroaryl-substituted Carbodiimides

N-α-Heteroaryl-substituted iminotriphenylphosphoranes react with phenylisocyanate, phenylisothiocyanate, and carbon disulfide to symmetrical and unsymmetrical α-heteroarylcarbodiimides.These can not be isolated as monomeres because they behave as 1.3-diazabutadienes predominantly and form 4+2-cycloadducts.The monomeric intermediates cyclodimerize to the 1.3.5-triazines 5 resp. 14 or react by the same scheme both with phenylisocyanate and with phenylisothiocyanate to give the 1.3.5-triazines 4, resp. 12.In competition with this reaction a 2+2-cycloaddition takes place, hence there follow numerous by-products.The structure of 1.3.5- triazines is determined from hydrolysis to guanidines 6 and on the basis of spectroscopic methods.

Formation of Cycloadducts from Heterocyclic Formamidines and Phenyl Isocyanate

Heterocyclic formamidines react with phenyl isocyanate at room temperature to give a cycloadduct which decomposes at elevated temperatures in two different ways; phenyl isocyanate reacts with the heterocyclic isocyanate formed in situ to form a new cycloadduct, a fused 1,3,5-triazine-2,4-dione derivative.
