Hyperbranched Polymers Based on Aliphatic Polyesters – Synthesis and Characterization
(Saarbrücken, Deutschland : VDM Verlag Dr. Müller Aktiengesellschaft & Co. KG, 2008)
Two series of hydroxy-functional hyperbranched polymers based on aliphatic polyesters have
been prepared from the 2,2-bis(hydroxymethyl)propionic acid (AB2 monomer) and the ditrimethylolpropane
(B4 functional core). A ...
Thermal behaviour of Ag/PMMA nanocomposites synthesized by in situ method
(Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2008)
The influence of the surface modified silver nanoparticles (Np), used as a filler, on the thermal properties poly(methylmethacrylate) (PMMA) matrix, synthesized by “in situ” radical polymerization process, was studied. The ...
A Novel Access to Tetrahydro β-Carbolines via One-Pot Hydroformylation / Fischer Indole Synthesis: Rearrangement of 3,3- Spiroindoleninium Cations
(American Chemical Society (ACS), 2008)
The two component one-pot hydroformylation/Fischer indole synthesis sequence of 2,5 dihydropyrroles and phenyl hydrazines allows a facile and convenient access to tetrahydro-β-carbolines in moderate to good yields.
Change of water redox potential, pH and rH in contact with magnesium enriched kaolinite–bentonite ceramics
(Elsevier, 2008)
It was established that the addition of Mg to the mixtures of kaolinite and bentonite can provide clay compositions which, after
sintering at high temperatures, produce very porous ceramics with microcrystalline and ...
Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis
(Royal Society of Chemistry, 2008)
Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. ...
1,2-Dithioles
(Elsevier, 2008)
The chemistry of 1,2-dithioles, 1,2-dithiolanes, 1,2-dithiolium salts, naphtho[1,8-cd]-1,2-dithiole, and 3,3aλ4,4-trithia-1-azapentalene is updated for the period 1995–2006. All X-ray determinations of structures containing ...
Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
Physicochemical Characterization of Carrageenans - A Critical Reinvestigation
(Wiley, 2008)
Kappa-, iota-, and lambda-carrageenan
(food grade) were analyzed by static light scattering
(MALS in batch mode) in 0.1M NaNO3 at 25 and 60 C,
earlier heated up to 90 C or not. At 25 C, there was a
strong tendency ...
