Carbodiimides unsym

Disubstituted tetrazolium salts (78) can be deprotonated with tri-ethylamine (70TL3453). Fragmentation of the resulting betaines gives car-bodiimides, and, since the tetrazolium salts can be prepared with a variety of substituents R , this provides a method for the generation of unsym-metrical carbodiimides with unusual substituents (e.g., R = vinyl or diethylamino). [Pg.63]
