1. A study has been made of the reaction of hydrogen isotope exchange in CF3COOD byη6-C6H6Cr(CO)2(η2-C4H2O3),η6-(CH3)3C6H3Cr(CO)2(η3-C4H2O3), andη6-C6H6Cr(CO)3, at 70°C. It has been found that the maleic anhydride does not have any great effect

It has been reported in [1-3] that the P=O group shows marked electron-acceptor activity in isotopichydrogen exchange (IHE) between triferrocenylphosphine oxide (Fc3P0)* and CF3COOD. We have continued earlier work in this field by studying IHE in tri

1. Ammoniate ions CrNH3+, Cr(NH3)2+ and C6H6CrNH3+ are formed upon the electron bombardment of a mixture of benzenechromium tricarbonyl and ammonia vapors. 2. The formation of the C6H6CrNH3+ ion in this system is possible only from carbonyl-containin

When the acidity function H0 is varied from +1 to −2.5, the rate of the isotopic exchange of hydrogen of benzenechromiumdicarbonylphenylphosphine is directly proportional to the acidity of the medium, while in the case of higher acidities from −2
