(p-Dimethylaminophenyl) Diphenylphosphine: A More Practical Phosphine in the Mitsunobu Reaction

Abstract
The Mitsunobu reaction has been of much use in general synthetic organic chemistry. The major drawback of this reaction has been the removal of the by-products triphenylphosphine oxide and the dialkyl hydrazinedi-carboxylate. We report here that (p-dimethylaminophenyl)diphenylphosphine, an alternative phosphine, greatly assists the work-up procedure of this useful reaction.
