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.
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.
Phosphites are oxidized to phosphate esters: P(OR) 3 + [O] → OP(OR) 3. This reaction underpins the commercial use of some phosphite esters as stabilizers in polymers. [6] Alkyl phosphite esters are used in the Perkow reaction for the formation of vinyl phosphonates, and in the Michaelis–Arbuzov reaction to form phosphonates.
In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4. The term also refers to the trivalent functional group OP(O-) 3 in such esters.
Triethyl phosphate is an organic chemical compound with the formula (C 2 H 5) 3 PO 4 or OP(OEt) 3. It is a colorless liquid. It is a colorless liquid. It is the triester of ethanol and phosphoric acid and can be called "phosphoric acid, triethyl ester".
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.
Tris(trimethylsilyl)phosphine is prepared by treating trimethylsilyl chloride, white phosphorus, and sodium-potassium alloy: [2] 1/4 P 4 + 3 Me 3 SiCl + 3 K → P(SiMe 3) 3 + 3 KCl
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.
