Haloalkanes: Grignard reagent

Principle

Haloalkanes react with magnesium to the so-called Grignard reagents in accordance with the general formula RMgX. With X = bromide or iodide, the reaction works best. Chlorides are usually more inert and require higher temperatures and longer reaction times for the conversion. The compounds that were discovered by Victor Grignard probably exist as dimeric structures.

Benefits

• Secure connection of the items by GL screw joint system
• Stable and safe setup due to solid stand material
