The 13C NMR chemical shifts have been determined for compounds of the type Cp2M(OG6H4R-P) 2[Cp=η5-C5H5; M=Ti, Zr and Hf; R=H, Me, MeO, Cl, Br and I].It was shown that the 13C NMR chemical shift of cyclopentadienyl ring moved npfield ae the metal descending down the periodic column.In addition, there is a good linear correlation among the 13C NMR chemical shifts of the corresponding carbon atoms in the three aeries of Ti, Zr and Hf compounds containing both phenyl and cyclopentadienyl rings.The correlation coefficient obtained by least-square method is 0.99 or better.
