The structure of a typical methoxy group. In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen.This alkoxy group has the formula R−O−CH 3.
Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
Methoxymethanol forms spontaneously when a water solution of formaldehyde and methanol are mixed. [3] [1] or when formaldehyde is bubbled through methanol.[4]In space methoxymethanol can form when methanol radicals (CH 2 OH or CH 3 O) react.
Potassium methoxide is a white to yellowish, hygroscopic, odorless crystalline powder which reacts violently with water forming potassium hydroxide and methanol.
Methyltrimethoxysilane is usually prepared from methyltrichlorosilane and methanol: . CH 3 SiCl 3 + 3 CH 3 OH → CH 3 Si(OCH 3) 3 + 3 HCl. Alcoholysis of alkylchlorosilanes typically proceeds via an S N 2 mechanism.
Alkali metal alkoxides are often oligomeric or polymeric compounds, especially when the R group is small (Me, Et). [3] [page needed] The alkoxide anion is a good bridging ligand, thus many alkoxides feature M 2 O or M 3 O linkages.
The hydroxymethyl group is a substituent with the structural formula −CH 2 −OH.It consists of a methylene bridge (−CH 2 − unit) bonded to a hydroxyl group (−OH).This makes the hydroxymethyl group an alcohol.
