Facile and highly efficient light-induced PR3/CO ligand exchange: A novel approach to the synthesis of [(μ-SCH2NnPrCH2S)Fe2(CO)4(PR3)2]
摘要:
A straightforward and efficient transformation of the Fe-S complex [(mu-SCH2N"PrCH2S)Fe-2(CO)(6)] to its double phosphine coordinated analogues [(mu-(SCH2NPrCH2S)-Pr-n)Fe-2(CO)(4)(PR3)(2)] (R = Ph, Me) is described. The single crystal structure of the PPh3-disubstituted Complex [(mu-(SCH2NPrCH2S)-Pr-n)Fe-2(CO)(4)(Ph3P)(2)] (3) showed that both of the phosphine ligands take an apical/apical instead of a basal/ basal or an apical/basal configuration.
