Treatment
of decaallylferrocene (<b>1</b>) with the Grubbs-II
catalyst in refluxing dichloromethane has promoted the 5-fold ring-closing
metathesis in <b>1</b> to afford single-bridged bis(1,4,5,8-tetrahydrofluorenyl)iron(II)
species <b>3</b> in excellent yield. The preferential formation
of <b>3</b> over quintuply bridged “superferrocenophane” <b>2</b> was explained as the intraannular RCM process being preferred
over the interannular one in the reactions of polyallylferrocenes.
