摘要：

Dicyclohexyl- and diphenylphosphanyl-substituted phosphaferrocenes 2 and 3 were synthesized by substitution of the amino group in 2-dimethylaminomethyl-3, 4-dimethylphosphaferrocene 1. Homologization of 2-formyl-3, 4-dimethylphosphaferrocene 4 by one CH2 unit via Wittig olefination provided access to the phosphanylethyl derivative 9. Ligands 2, 3 and 9 formed P,P-chelate complexes with tetracarbonyl metal fragments in good yield. X-ray crystal structure determinations were carried out for five-ring chelate complex 2. Mo(CO)(4) (= 10), and the six-ring chelate complex 9 . Mo(CO)(4) (= 13).
