α-Substituted Phosphonates. 40. 1-Trimethylammonium-1-diethylphosphono-1-cyanomethylid, a Stable N-YlidDiethyl-1-dimethylamino-1-cyanomethanephosphonate 4 can be alkylated on nitrogen to the quarternary ammoniumsalts 5, which by C-deprotonation gives the stable N-ylid 8. The N-ylid 8 behaves inert against carbonyl compounds and acylating agents, but can be C-alkylated and - involving an ester-dealkylation - C-chlorinated.
