UEBERGANGSMETALL-HETEROALLEN-KOMPLEXE XVII. REAKTIONEN DES AZA-ALLYL-KOMPLEXES (KETENIMIN)Fe2(CO)6 MIT PHOSPHANEN

Article abstract of DOI:10.1016/0022-328X(87)80230-9

The aza-allyl complex (ketene imine)Fe2(CO)6 (3a) reacts with phosphanes PR3 to give substitution products of the type (ketene imine)Fe2(CO)5PR3 (4a,b).In addition, the phosphane PMe3 yields a ferrole complex (5).Phosphites react with complex 3a to form mono- and di-substitution products (ketene imine)Fe2(CO)5P(OR)3 (4c, d) and (ketene imine)Fe2(CO)4(P(OR)3)2 (6).Diphosphanes yield substituted complexes of type (ketene imine)Fe2(CO)4(μ-Ph2P-PPh2) (7).The structures of (ketene imine)Fe2(CO)5PMe3 (4a), the ferrole complex 5, and (ketene imine)Fe2(CO)4(μ-Ph2PCH2CH2PPh2) (7b) were determined by X-ray analysis.
