Alcohols phosphates

These mixed phosphate ester titanium complexes or their amine salts are useful as fuel additives to help maintain cleanliness of carburetors and inhibit surface corrosion. Chloride-free mixed alcohol phosphate esters can be obtained if a tetraalkyl titanate is used (101). 

One of the most impressive findings has been the discovery of lipid intermediates in the biosynthesis of polysaccharides (see Refs. 2 and 465.) At least two structurally different types of these compounds exist the intermediate may be an isoprenoid alcohol ester of the glycosyl pyrophosphate or the analogous derivative of the glycosyl phosphate. Derivatives of the first type are formed by reaction between the sugar nucleotide and the alcohol phosphate, for example, undecaprenyl phosphate (120), which participates in the biosynthesis of Salmonella lipopolysaccharide.466... 

Exercise 20-18 From the discussion in Section 15-5F, it should be clear that the reaction of an alcohol phosphate with ADP to give ATP, ROPO320+ ADP -—=> ATP + ROH, is not likely to have a favorable equilibrium constant. Explain why one might expect the following reaction to be more energetically favorable. 

In scientific and patent literature on diene polymerization the following Nd(III)-salts are most often cited as catalyst precursors halides, carboxylates, alcoholates, phosphates, phosphonates, allyl compounds, cyclopentadienyl derivatives, amides, boranes and acetylacetonates. The catalyst systems based on these Nd-sources are reviewed in the following subsections. 

Lanthanide halide complexes free of coordinated Lewis bases, such as alcohols, phosphates, amines, dimethylsulfoxide, or THF, suffer from low solubilities in non-coordinating solvents. Therefore, catalytic systems based on LnCl3 generally require preformation or aging in order to reach maximum activities. In contrast, lanthanide tetrahalogenoaluminate complexes are soluble in aromatic solvents. Such simple Ln/Al heterobimetallic halide...

BURCO SCOUR CS-LF contains only linear alcohol phosphates and nonionics. Based on literature evaluations this product should be fully biodegradable. 

To obtain an even better model compound for the corresponding deoxyribose-centered radical in DNA, ether phosphates were used instead of the alcohol phosphates described in reaction 23. For example, on reaction of OH with 2-methox-yethylphosphate at pH 4.5 the 2-yl radical is the most prominent species (see Scheme 10), as observed by ESR [89]. By measuring the coupling constants as a function of pH, the pATa of the radical was determined to be 6.5. On reducing the pH, the 2-yl radical disappeared giving rise to two product radicals, as shown below (Scheme 10). 

Lund [280] observed that reduction of 4-chloroquinazoline in an alcoholic phosphate buffer results in the two-electron cleavage of the carbon-chlorine bond with formation of quinazoline in essentially quantitative yield. 

Antistatic agent can also be called antistat in the industry. The best antistatic agents used in fibre finishes are quaternary amines and alcohol phosphate esters. For example, A-cetyl-A-ethylmorpholinium ethylsulphate shown in Fig. 5.8a and stearyl alcohol phosphate shown in Fig. 5.8b are representative antistats.

Auto oxidation of 6,7-diphenyl-5-methyl-5,6,7,8-tetrahydropterin (112) in alcoholic phosphate buffer gave tetrahydro-4ff,9/f-pyrazino[l,2-a][l,3,5]triazine (113) and then (26) (Scheme 14). The auto-oxidation of (113) in water proceeded at an inconveniently slow rate, but was faster in alkali. Oxidation with 02 in aqueous alkaline (H2 0) indicated the incorporation of heavy oxygen into the system <75T54i>. 

At one time, the lipid carrier was believed to be a glycerophos-phatide, but further purification showed conclusively that it is a Cjs-isoprenoid alcohol phosphate. Its nuclear magnetic resonance spectrum showed that two of its internal double bonds have the trans configuration, and that this isoprenoid alcohol differs from ficaprenol, a Cjs-isoprenoid alcohol from fig leaves, which has three internal, trans, double bonds. ...
