Abstract

Abstract. Nr-Heteroaryl-substituted iminotriphenylphosphoranes react with phenylisocyanate, phenylisothiocyanate, and carbon &sulfide to symmetrical and unsymmetrical cx-heteroarylcarbodiimides. These can not be isolated as monomeres because they behave as 1.3-diitxabutadienes predominantly and form 4+ 2-cycloadducts. The monomeric intermediates cyclodimerize to the 1.3. 5-triaxines 5 resp. 14 or react by ...
