Imidazole Derivatives, XVII. – Synthesis and Properties of Dichloro(1,3‐dimethyl‐2‐imidazol‐2‐ylidenimino)phosphane – a Methylenamino Substituent with Uncommon Donor Properties Dichloro(1,3‐dimethyl‐2‐imidazol‐2‐ylidenimino)phosphane ( 5 ) is obtained from 1,3‐dimethyl‐2,3‐dihydro‐2‐trimethylsilyliminoimidazole ( 4 ) and PCl 3 in almost quantitative yield. Strong PN‐π interaction ( 5B ) is revealed by its X‐ray structure analysis [P(1)–N(1) 1.579(2) Å]. AlCI 3 causes chloride abstraction to give the cationic cyclophosphazane 8 identified by NMR spectroscopy.
