Studies on organolanthanide complexes: XXXVII. Reaction of dicyclopentadienylyttrium chloride with acyl chlorides in tetrahydrofuran. Acylative cleavage of the Cp-Y π-bond and tetrahydrofuran ring

Abstract Dicyclopentadienylyttrium chloride reacts with aromatic and aliphatic acid chlorides in tetrahydrofuran at room temperature, resulting in cleavage of the CpY π-bond to produce 1,5-diacylcyclopentadienes, and the acylative ring-opening of tetrahydrofuran. A possible reaction mechanism is proposed.
