Synthesis of dialkyl(aryl)cyclobutenylphosphine oxides
摘要:
Dialkyl(aryl)cyclobutenylphosphine oxides are obtained via two routes: from the corresponding cyclobutenylphosphonic dichlorides using organomagnesium chemistry and from 1,3-dienylphosphine oxides by thermal electrocyclic ring closure. (C) 2012 Elsevier Ltd. All rights reserved.
