Methiodide

Source: Wikipedia, the free encyclopedia.

In organic chemistry, a methiodide is a chemical derivative produced by the reaction of a compound with

tertiary amines
:

R3N + CH3I → (CH3)R3N+I

Whereas the parent amines are hydrophobic and often oily, methiodides, being salts, are somewhat hydrophilic and exhibit high melting points. Methiodides exhibit altered pharmacological properties as well.

Examples include:

Tertiary phosphines and phosphite esters also form methiodides.[2]
