Camphor-based β-hydroxyphosphoryl ligands and their complexes of the type [MoO(O2)2L(H2O)]
Abstract
Homochiral hydroxyphosphoryl compounds, L, such as the novel camphor-based (1R)-endo,endo-3S-(diphenylphosphoryl)-2R-hydroxybornane, have been found to be prevented from behaving as bidentate ligands in the epoxidation catalysts [MoO(O2)2L(H2O)] by unexpectedly strong multiple-bond delocalisation producing near linear Mo–O–P angles.
