orus ylide 1. (A) Azide-free diazo transfer to symmetrical (2a) and unsymmetrical (2b) carbodiphosphoranes. Base: KHMDS (for 2a), NaNH2 (for 2b). (B) Mechanistic 5 simulations at the (B3LYP-D3(BJ)/def [...] carbon is a particularly formidable challenge. Here we report a straightforward, azide-free 10 synthesis of a crystalline and isolable diazophosphorus ylide Ph3PCN2, a stable compound with a carbon atom [...] phorane containing PPh3 and P nBu3 entities (2b) was synthesized as a yellow oil in three steps. 10 Exposure of carbodiphosphorane 2b to N2O results in a formal N2/P nBu3 exchange to afford the target …
