Phenyl dihydrogen phosphate

Phosphorylation.1 Alkyl(phenyl) dihydrogen phosphates (3) are prepared conveniently in fair to good yield by the following sequence. The reaction of an alcohol (or phenol) with the reagent (1) in THF in the presence of pyridine at—20° and subsequent hydrolysis with water and a trace of pyridine at 15° yields the diester (2). The O-protective group in (2) is then eliminated by hydrolysis with pyridine—water at 80° to give (3). [Pg.27]

An alternative approach involved combining monodecyl dihydrogen phosphate (73) or mono-[4-(l, 1,3,3-tetramethylbutyl) phenyl] dihydrogen-phosphate (77) with the hydroxyl groups of a partially hydrolysed vinyl choride-vinyl acetate copolymer (copolymer VAGH, relative molecular... [Pg.113]

The substitution path b) (Eq. (94) ), is favored by the following experimental conditions low current density, grapliite as anode material, alkaline medium, water or water-pyridine as solvent, and admixture of foreign ions e.g., bicarbonate, sulfate, perchlorate, dihydrogen phosphate, Pb2+, Mn2+, Cu2+, Fe2+, Co2+. The carbonium ion path b) can furthermore be expected for carboxylates RR CHOO with a-substituents R such as alkyl, phenyl 198 hydroxy, halogen 1 amino, or alkoxy. These substituents facilitate oxidation of the intermediate alkyl radical R to the carbonium ion R+. Product formation occurs via carbonium ions and not, as is also conceivable, via mixed coupling of R with Nu ... [Pg.63]

Noordam et al. with a phenyl type of stationary phase reduced the analysis time, whilst Improving peak shapes and resolution of pilocarpine and its degradation products. As mobile phase, 5% potassium dihydrogen phosphate (pH 2.5) in water was found to be the most suitable. [Pg.421]

The hydrolyses of sodium di-4-nitrophenyl phosphate and lithium ethyl 4-nitrophenyl phosphate at pH 5.8-8.3 and 75° are catalyzed by Cu(bpy) by factors of 2000 and 150, but much greater catalytic effects by metal ions are to be seen in the hydrolysis of 2-(1,10-phenanthryl) dihydrogen phosphate in aqueous solution by divalent metal cations, the maximum effect being seen with copper)II) when the hydrolysis is faster than that of phenyl phosphate and 3-nitrophenyl phosphate dianions by factors of 10 and 6 x 10 respectively. ...

Steroids possessing one or two isolated or conjugated double bonds are converted into their dihydrogen phosphates when brought into contact with (l-phenyl-l,2-dibromoethyl)phosphonic acid in the presence of ethyldiisopropyl-amine. The reactions presumably involve monomeric metaphosphate ion as the effective phosphorylating agent. ... [Pg.106]
