PRODUCT INTRODUCTION
description
Triphenylphosphane oxide is a phosphine oxide in which the substituents on phosphorus are three phenyl groups.It is one of the more common phosphine oxides. This colourless crystalline compound is a common but potentially useful waste product in reactions involving triphenylphosphine. It is a popular reagent to induce the crystallizing of chemical compounds.
