In nature, methoxy groups are found on nucleosides that have been subjected to 2′-O-methylation, for example in variations of the 5′-cap structure known as cap-1 and cap-2. They are also common substituents in O -methylated flavonoids , whose formation is catalyzed by O-methyltransferases that act on phenols , such as catechol- O -methyl ...
2,2-Dimethoxypropane (DMP) is an organic compound with the formula (CH 3) 2 C(OCH 3) 2. A colorless liquid, it is the product of the condensation of acetone and methanol. DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2]
Trimethyl borate is the organoboron compound with the formula B(OCH 3) 3 and a metal alkoxide. It is a colourless liquid that burns with a green flame. [1] It is an intermediate in the preparation of sodium borohydride and is a popular reagent in organic chemistry.

The nitroso group has both a +M and -M effect, but the -M effect is more favorable. Nitrogen has a lone pair of electrons. However, the lone pair of its monomer form is unfavourable to donate through resonance. Only the dimer form is available for +M effect. However, the dimer form is less stable in a solution.

[2] Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons. It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process.
