Syntheses of iron-containing heterometallic complexes using tridentate phosphine ligands; the crystal structure of [(OC)3Fe{(Ph2P)2CHCH2PPh2}Ru3(CO)9{Ph2PC(CH2)PPh2}]
摘要:
Treatment of [Fe(CO)3(dppee)] [dppee = 1,1 -bis(diphenylphosphino)ethene] with PPh2H gives the addition product [Fe(CO)3{(Ph2P)2CHCH2PPh2}] 1. The unco-ordinated phosphine group of complex 1 reacts with [{RhCl(CO)2}2] to give [(OC)4Fe{Ph2PCH(PPh2)CH2PPh2}RhCl] 3 via [(OC)3Fe-{(Ph2P)2CHCH2PPh2}Rh(CO)Cl2Rh(CO)2] 2. Complex 1 reacts with [Ru3(CO)10(dppee)] to give the heterometallic complex [(OC)3Fe{(Ph2P)2CHCH2PPh2}Ru3(CO)9(dppee)] 4 the structure of which has been determined by X-ray crystallography.
