文摘

The ferrocenyl-substituted phosphaheterocycles racemic 1-(1,3,2-dithiaphosphorinan-2-yl)-2-N,N-dimethylaminomethylferrocene (rac-4) and racemic 1-(1,3,2-dioxaphosphorinan-2-yl)-2-N,N-dimethylaminomethylferrocene (rac-5) have been prepared and their coordination chemistry has been studied. Compounds rac-4 and rac-5 act as bidentate P,N ligands in rac-[Mo(CO)₄(4-魏P,N)] (rac-6) and rac-[Mo(CO)₄(5-魏P,N)] (rac-7), and as monodentate ligands in rac-[RuCl₂(5-魏P)(畏⁶-cymene)] (rac-8) and rac-[AuCl(4-魏P)] (rac-9). Compounds rac-4 to rac-9 were fully characterised by NMR (¹H, ¹³C, ³¹P) and IR spectroscopy, mass spectrometry, single-crystal X-ray crystallography, and elemental analysis. Furthermore, preliminary studies on rac-5 in the rhodium(I)-catalysed hydroformylation of ethyl methacrylate were carried out and showed a preference for the branched aldehyde.
