[4+2+2] Cycloaddition catalyzed by a new cationic rhodium–bisphosphine monooxide complex†
Abstract
A rhodium–BozPHOS based complex is reported. This complex is competent in catalyzing the [4+2+2] cycloisomerization of cyclooctatrienes in moderate to good yields. The X-ray crystal structure of this complex is reported, along with formation of both bicyclic and tricyclic cyclooctatrienes.
