Abstract

The title compounds CpCrR2(PR3′) (R = CH3, CH2C6H5, CH2SiMe3) and CpCr(CH3)2(PMe3) (3b) have been prepared, and a piano‐stool geometry has been established for 3b by X‐ray structure analysis. Convenient observation of the hydrogen atoms 1′‐H of R is only possible by 2H NMR giving signals which are up to 6200 Hz broad and shifted up to –1373 ppm.
