  2. Trimethyl phosphite - Wikipedia

    en.wikipedia.org/wiki/Trimethyl_phosphite

    P(OCH 3) 3 → CH 3 P(O)(OCH 3) 2. As a ligand, trimethyl phosphite has a smaller cone angle and better acceptor properties relative to trimethylphosphine. A representative derivative is the colorless tetrahedral complex Ni(P(OMe) 3) 4 (m.p. 108 °C). [4] The tridentate ligand called the Kläui ligand is derived from trimethyl phosphite. The ...

    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. Inversion of the configuration is favored during nucleophilic attack when displacing good leaving groups, such as chloride. [3] In contrast, displacement of poor leaving groups, such as alkoxide, retention is ...

    en.wikipedia.org/wiki/Methoxy_group

    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 ...
