The reaction of the diarylphosphine oxide anion with oxiranes: a new synthesis of 1,2-ethylenebis(diarylphosphine oxides)
Abstract
In an unusual double-substitution reaction, the diarylphosphine oxide anion reacts with oxiranes to give bis(phosphine oxides) that can have functional groups on the aryl ring and/or the bridging carbons between the PO groups.
