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. Several other methods exist. [1] Copper phosphide cluster Cu 96 P 30 {P(SiMe 3) 2} 6 (PEt 3) 18 with C and H atoms omitted for clarity (red=Cu, purple=P, tan=Si ...
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 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.
Diethyl phosphite hydrolyzes to give phosphorous acid. Hydrogen chloride accelerates this conversion.: [2] Diethyl phosphite undergoes transesterification upon treating with an alcohol. For alcohols of high boiling points, the conversion can be driven by removal of ethanol: [8] (C 2 H 5 O) 2 P(O)H + 2 ROH → (RO) 2 P(O)H + 2 C 2 H 5 OH
A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry.This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule.
Dimethylphosphite is an organophosphorus compound with the formula (CH 3 O) 2 P(O)H, known as dimethyl hydrogen phosphite (DMHP). Dimethylphosphite, is a minor tautomer of the phosphorus(V) derivative. It is a reagent for generating other organophosphorus compounds, exploiting the high reactivity of the P-H bond. The molecule is tetrahedral. It ...
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.
Phosphonate natural product antibiotics include fosfomycin which is approved by FDA for the treatment of non-complicated urinary tract infection as well as several pre-clinically investigated substances such as Fosmidomycin (inhibitor isoprenyl synthase), SF-2312 (inhibitor of the glycolytic enzyme enolase, [6] and substances of unknown mode of ...
