Betulin 3,28-di-O-tosylate
The title compound, C44H62O6S2 {systematic name: (1R,3aS,5aR,5bR,7aR,9S,11aR,11bR,13aR,13bR)-5a,5b,8,8,11a-penta-methyl-1-(prop-1-en-2-yl)-3a-[(tos-yloxy)meth-yl]icosa-hydro-1H-cyclo-penta-[a]chrysen-9-yl 4-methyl-benzene-sulfonate}, was obtained by tosyl-ation of naturally occurring betulin. All the cyclo-hexane rings adopt chair conformations and the cyclo-pentane ring adopts a twisted envelo...
متن کاملO,O′-Di-p-tolylpyrophosphoric bis(dimethylamide)
The title compound, C(18)H(26)N(2)O(5)P(2), was obtained accidently from the reaction between N,N-dimethyl-phospho-ramido-chloridic acid 4-methyl phenyl ester, NaNO(2) and 18-crown-6 in acetonitrile under reflux conditions. The asymmetric unit contains one half-mol-ecule, the complete mol-ecule being generated by crystallographic twofold symmetry, with the bridging O atom lying on the rotation ...
متن کاملSynthesis, Characterization and Antibacterial Activity of mono-, di- and tri-tosylate of Glycerol
Glycerol is a valuable co-product from oleochemical industry such as from fatty acid and biodiesel production. By having three hydroxyl groups in its molecule, glycerol can undergo chemical modifications that lead to many possible applications. This paper reports the tosylation process of glycerol with para-toluenesulfonyl chloride (p-TsCl). Reaction of glycerol with p-TsCl in the presence of a...

In the title compound, {(C(10)H(11)N(3))[Zn(3)(C(8)H(4)O(4))(4)]·2H(2)O}(n), divalent Zn atoms are linked into trinuclear units featuring tetra-hedral, octa-hedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn(3)(isophthalate)(4)](n) (2n-) anionic layers, which aggregate into the three-di...
متن کامل1392-1398 Rashedi 328
INTRODUCTION Protect the oil wells to increase their longevity is now one of the major oil-producing countries is difficult. Each year, an extraordinary global budget for research on EOR and MEOR (enhanced oil recovery methods) is allocated. In addition, the owners of these vessels extraordinary efforts to exploit new, lower cost, and highly efficient techniques. A new and promising way to incr...
