Treatment of the cationic secondary (phosphane)iron complexes [(RЈC 5 H 4 )(OC) 2 Fe-P(R)H 2 ]BF 4 [R = tBu, Ph, Mes; RЈ = H, neomenthyl (NM)] (4a-e) with 2 affords the complex 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 salts {(RЈC 5 H 4 )(OC) 2 Fe-P(R)(H)[N(H)-N=C(H)CO 2 Et]}BF 4 (5a-d) or {(RЈC 5 H 4 )(OC) 2 Fe-P(R)[N(H)-N=C(H)CO 2 Et] 2 }BF 4 {Cp(OC) 2 Fe-P(Ph)(R)[N(H)-N=C(H)CO 2 Et]}BF 4 (R = Ph, Me) ( ) by insertion of the terminal nitrogen atom of 2 into the (6a-d), depending on the molar ratio. The structures of 5c and 6b are proved by X-ray analysis. P-H bond of 1a, b. Reaction of the primary (phosphane)iron [᭛] Part LXI: Ref.
