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

[image omitted] In a short reaction time, acyl chlorides and dry tetrahydrofuran react in the presence of a catalytic amount of magnesium turnings (Mg) at 25 degrees C to give 4-chlorobutyl esters in excellent yields.
