Description

Zirconium(IV) chloride catalyzes the trans-hydrostannylation of acetylenes with Tri-n-butyl­tin hydride. It is used as a superior catalyst for the fries rearrangement of aryl acetates, giving the least hindered ortho-acetyl phenol in high yields at ambient temperatures. In the presence of ZrCl4, chloromethyl ethers are formed under mild conditions from acid chlorides and trioxane or paraformaldehyde.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
