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 ...
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.
Trimethyl phosphate is a mild methylating agent, useful for dimethylation of anilines and related heterocyclic compounds. [2] The method is complementary to the traditional Eschweiler-Clarke reaction in cases where formaldehyde engages in side reactions.
The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...
Dimethyl methylphosphonate can be prepared from trimethyl phosphite and a halomethane (e.g. iodomethane) via the Michaelis–Arbuzov reaction. [2]Dimethyl methylphosphonate is a schedule 2 chemical as it may be used in the production of chemical weapons.
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.
Trimethylphosphine is a highly basic ligand that forms complexes with most metals. As a ligand, trimethylphosphine's Tolman cone angle is 118°. [7] This angle is an indication of the amount of steric protection that this ligand provides to the metal that to which it is bound.
Trimethyl borate is the main precursor to sodium borohydride by its reaction with sodium hydride in the Brown-Schlesinger process: . 4 NaH + B(OCH 3) 3 → NaBH 4 + 3 NaOCH 3. It is a gaseous anti-oxidant in brazing and solder flux.
