Spectroscopic characterization and stereodynamics of ferrocenylselenoethers Pt(II), Pd(II), Rh(III) complexes

Ferrocenlyselenides (C5H5FeC5H4SeR, Fe(C5H4SeR)2) and their complexes of metal Pt, Pd, Rh (R=undecenyl, benzyl, phenyl) have been prepared. The spectroscopic characterization has been examined by mass spectrum, XPS, IR and NMR. IR, NMR spectra of C5H5Fe C5H4Se (CH2)9 CH=CH2PtCl2 reveal C=C double-bond in Fe(C5H4Se (CH2)9CH=CH2)2 Pt Cl2 is free because of binding with Pt(II). The results obtained fromH,13C and77Se NMR indicate that invertomers ofmeso anddl species existence. The ratio ofmeso/dl for BUnSeF Pt is ca 70/30, whereas four and three invertomers for BUnSeF Pt and BBSeFPd have been clearly observed from1H NMR spectra.
