(Геозавод, 2005)
There were calculated contents of the phases with smaller ionic radius in the SrCO3-PbCO3, SrCO3-BaCO3 and PbCO3-BaCO3 systems for the three-component SrCO3-PbCO3-BaCO3 system.
Results of these mathematical calculations ...
Crystallographicaly-chemical characteristics of sphalerites from the polymetallic Pb-Zn ore deposit Kiževak (Raška, Serbia)
(Минно-геоложки университет “Св. Иван Рилски”, 2004)
With the X-ray, chemical and spectrochemical methods there were investigated monomineral concentrations of sphalerites from the polymetallic Pb-Zn ore deposit Kizevak (Raska, Serbia).
These sphalerites are from the different ...

X-ray investigations of arsenopyrites from some ore deposits of Serbia
(Geoinstitut, 2003)
With the X-ray investigations there were examined arsenopyrites from five ore deposits of Serbia: Crveni Breg (Avala), Rudnik (Rudnik), and Sastavci, Belo Brdo and Trepča (Kopaonik). Investigations involved qualitative ...
Occurence of alunite and natroalunite at Veliki Bukovik (Raška, Serbia)
(Минно-геоложки университет “Св. Иван Рилски”, 2004)
Alunite and natroalunite from Veliki Bukovik near Raska (Serbia) were determined. There were obtained following unit cell dimensions and crystallochemical formulas:
alunite: a0=6.976(1)Å; c0=17.295(6)Å; V0=729.0(3)Å3; ...
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. ...
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 ...
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.
