A mild, broadly functional group tolerant methodology has been developed to access a variety of mono- and bis-carbodiimides in good yield and high purity on multigram scale. Direct addition into these versatile motifs facilitated the rapid synthesis of a library of novel amidinines, guanidines, and phosphaguandines.

An efficient palladium-catalyzed cross-coupling reaction of azides with isocyanides is developed, providing a general synthetic route to unsymmetric carbodiimides with excellent yields. This method shows a broad substrate scope, including not only aryl azides, but also unactivated benzyl and alkyl azides. Furthermore, from readily available substrates, Pd-catalyzed coupling with a tandem amine insertion cascade to obtain unsymmetric trisubstituted guanidines has been achieved in a one-pot fashion.

A new method is described for the preparation of carbodiimides by dehydration of ureas with arenesulfonyl chlorides under solid-liquid phase-transfer catalytic (PTC) conditions using solid potassium carbonate as a base and a lipophilic quaternary ammonium salt as a catalyst.The method is generally applicable for the synthesis of disubstituted carbodiimides, but is especially useful for unsymmetrically substituted carbodiimides.The basic carbodiimides prepared were identified in the form of the more stable, crystalline quaternary salts.
