Intramolecular Barbier reaction in water: Cyclopentane and cyclohexane ring closure / Intramolekulska Barbier-ova reakcija u vodi - sinteza petočlanih i šestočlanih prstenova
(Serbian Chemical Society, 2002)
Zinc or indium promoted intramolecular Barbier reactions of aldehydes containing a suitably positioned allylic or propargylic halide unit afford unsaturated cyclic alcohols in moderate yields.
Regioselectivity of conjugate additions to monoalkyl-1,4-benzoquinones / Regioselektivnost konjugovane adicijena monoalkil-1,4-benzohinone
(Serbian Chemical Society, 2002)
The regioselectivity of the reaction of conjugate addition of thiols amines, methanol and hydrogen chloride with the monoalkyl-1,4-benzoquinones avarone and 2-tert-butyl- 1,4-benzoquinone was investigated. It was shown ...
An estimation of the interfacial energy of the copper-copper sulphate solution interface and of the specific surface of copper powder / Procena međupovršinske energije bakar-rastvor bakar sulfata i specifične površine bakarnog praha
(Serbian Chemical Society, 2002)
Apossible way for the estimation of the interfacial energy of the copper – copper sulphate solution interface is proposed. The estimated value of (2.7±0.3) J cm-2 and the derived equations which relate the specific surface ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
The retention behaviour of some cholic acid derivatives on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2002)
The thin-layer chromatographic behavior of cholic acid and fourteen of its synthetic derivatives has been studied in six reversed-phase and three normal-phase systems. Four significantly different adsorbents were used - ...
