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.
Dimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH 3 OCH 3, (sometimes ambiguously simplified to C 2 H 6 O as it is an isomer of ethanol). The simplest ether , it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for ...
Trimethyl orthoformate is a useful building block for creating methoxymethylene groups and heterocyclic ring systems. It introduces a formyl group to a nucleophilic substrate, e.g. RNH 2 to form R-NH-CHO, which can undergo further reactions.
Trimethyl phosphite is an organophosphorus compound with the formula P(OCH 3) 3, often abbreviated P(OMe) 3.It is a colorless liquid with a highly pungent odor. It is the simplest phosphite ester and finds used as a ligand in organometallic chemistry and as a reagent in organic synthesis.

Tetramethyl orthosilicate (TMOS) is the chemical compound with the formula Si(OCH 3) 4.This molecule consists of four methoxy groups bonded to a silicon atom. The basic properties are similar to the more popular tetraethyl orthosilicate, which is usually preferred because the product of hydrolysis, ethanol, is less toxic than methanol.
