摘要:
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(O-2)(2)L(H2O)] by unexpectedly strong multiple-bond delocalisation producing near linear Mo-O-P angles.
