Synthetic routes to PN 2 C 2 -heterocyclic cations
Nahil Al-Zuhaika, Jitian Chen, Elena Zelenco, Douglas W. StephanWhile phosphino-phosphenium and phosphirenium cations react with carbodiimides, the combination of PPh 2 Cl, AlCl 3 or K[B(C 6 F 5 ) 4 ] with carbodiimides, dimines or imines provides direct routes to salts of cationic five-membered PN 2 C 2 -rings.
