β¦ Synopsis
Very few examples of the preparation of phosphetanes (phosphacyclobutanes) or related derivatives have appeared in the literature (l), and relatively little is known about the chemical behavior of these systems. As recent investigations (2) have led to the synthesis of 2,2,3,4,4-pentemethyl-1-phenylphosphetane (I), the corresponding oxide II, and phosphonium salts, IIIa and IIIb, we now wish to describe the unusual behavior of II and III treatment with phenyllithium and III with dilute sodium hydroxide.
