Conclusions

  1. 1.

    Based on the data obtained in studying the IR and13P NMR spectra of chromium η6- arenecarbonyl complexes with a diphosphine ligand, C5H5Cr (CO) (Ph2P (CH2)2PPh2) and (CH3)3C6H3-Cr(CO) (Ph2P(CH2)2PPh2), it was established that in acid media these complexes are protonated at the chromium atom to give the cis and trans isomers.

  2. 2.

    The deuterium exchange of C6H6Cr(CO)(Ph2P(CH2)2PPh2) in CF3COOD was studied and it was established that this complex exchanges hydrogen for deuterium at a rate that is 10 times slower than that of 1,3,5-(CH3)3C6H3Cr(CO)(Ph2P(CH2)2PPh2).
