Some reactions of ferrocenyl phosphines with M3(CO)12 (M = Fe, Ru). The structures of Ru3(CO)11(PFcPh2) and Ru3(CO)10{(PPh2-η-C5H4)2Fe}

Substitution reactions of M 3 (CO) 12 (M = Fe, Ru) and Ru 4 ((μ-H) 4 (CO) 12 involving a range of ferrocenyl phosphines are described. Compounds isolated and characterized include Fe 3 (CO) 11 PFcPh 2 , Fe 3 (CO) 10 (PBuFcPh) 2 , Fe(CO) 4 L (L = PFc 2 Ph, PFc 3 ), Ru 3 (CO) 11 L (L = PFc 3 , PFc 2 Ph, PFcPh 2 ), Ru 3 (CO) 10 L 2 (L = PFc 2 Ph, PFcPh 2 ), and Ru(CO) 4 PFc 3 . Ru 4 ((μ-H) 4 (CO) 10 (LL) and Ru 3 (CO) 10 (LL) result from reactions with LL = (Ph 2 PC 5 H 4 ) 2 Fe. The structure of two derivatives are described.
