“…6 A number of discrete dioxo-Mo VI complexes react with oxygen atom abstractors like phosphines, and a common occurrence in the process is the formation of dimeric complexes (equation 1, where Tp* = hydrotris(3,5-dimethyl-pyrazol-1-yl)borate). 7,8,9,10,11,12,13,14,15 Unless the dinuclear compounds are in rapid equilibrium with the mononuclear compounds, formation of dinuclear compounds terminates the catalytic process. Two general approaches have been used to prevent the dinucleation.…”
