# Role of zinc chloride in reaction of ether

I am trying to do a reaction between acetyl chloride $$\ce{CH3COCl}$$ with diethyl ether. I know that upon using anhydrous $$\ce{ZnCl2}$$ and heat, I'll get an ester and an alkyl chloride, but I'm not able to guess the mechanism.

Does $$\ce{ZnCl2}$$ break the $$\ce{C-O}$$ bond in ether as it would've done to alcohol? Please help me with the mechanism.

• Yes I believe the ZnCl2 is used to cleave the ether first to give the alkyl chloride and an alkoxide. This alkoxide then goes on to attack the acyl chloride, giving the ester. – Tan Yong Boon May 27 '19 at 7:45
• I agree, the Zn2+ binds to the oxygen polarising the C-O bond enough for nucleophilic attack by Cl- at C. – Waylander May 27 '19 at 9:19
