Notes:
Treatment of the cationic secondary (phosphane)iron complexes [Cp(OC)2Fe-P(Ph)(R)H]BF4 (R = Ph, Me) (1a, b) with diazoacetic ester (2) yields the novel complex salts {Cp(OC)2Fe-P(Ph)(R)[N(H)-N=C(H)CO2Et]}BF4 (R = Ph, Me) (3a, b) by insertion of the terminal nitrogen atom of 2 into the P-H bond of 1a, b. Reaction of the primary (phosphane)iron complexes [(R′C5H4)(OC)2Fe-P(R)H2]BF4 [R = tBu, Ph, Mes; R′ = H, neomenthyl (NM)] (4a-e) with 2 affords the complex salts {(R′C5H4)(OC)2Fe-P(R)(H)[N(H)-N=C(H)CO2Et]}BF4 (5a-d) or {(R′C5H4)(OC)2Fe-P(R)[N(H)-N=C(H)CO2Et]2}BF4 (6a-d), depending on the molar ratio. The structures of 5c and 6b are proved by X-ray analysis.
