Treatment of the cationic secondary (phosphane)iron complexes [Cp(OC) 2 Fe–P(Ph)(R)H]BF 4 (R = Ph, Me) ( 1a , b ) with diazoacetic ester ( 2 ) yields the novel complex salts {Cp(OC) 2 Fe–P(Ph)(R)[N(H)–N=C(H)CO 2 Et]}BF 4 (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′C 5 H 4 )(OC) 2 Fe–P(R)H 2 ]BF 4 [R = t Bu, Ph, Mes; R′ = H, neomenthyl (NM)] ( 4a–e ) with 2 affords the complex salts {(R′C 5 H 4 )(OC) 2 Fe–P(R)(H)[N(H)–N=C(H)CO 2 Et]}BF 4 ( 5a–d ) or {(R′C 5 H 4 )(OC) 2 Fe–P(R)[N(H)–N=C(H)CO 2 Et] 2 }BF 4 ( 6a–d ), depending on the molar ratio. The structures of 5c and 6b are proved by X‐ray analysis.
