Synthesis, characterization, antioxidant and antimicrobial activity of novel 5-arylidene-2-ferrocenyl-1,3-thiazolidin-4-ones
(Journal of Organometallic Chemistry, 2018-08)
Synthesis of twenty novel 5-arylidene-2-ferrocenyl-1,3-thiazolidin-4-ones has been achieved in good to excellent yields by the Knoevenagel condensation of 2-ferrocenyl-1,3-thiazolidin-4-ones with aromatic aldehydes. The ...
Synthesis of novel multi-functionalized pyrrolidines by [3 + 2] dipolar cycloaddition of azomethine ylides and vinyl ketones
(Monatshefte fuer Chemie/Chemical Monthly, 2019-02)
An efficient and easy synthetic route to substituted pyrrolidine derivatives has been established through [3 + 2] dipolar cycloaddition of vinyl ketones and azomethine ylides. The reactions proceed smoothly, under mild ...
Synthesis, characterization and antimicrobial activity of novel 3-ferrocenyl-2-pyrazolyl-1,3-thiazolidin-4-ones
(Polyhedron, 2018-11)
A new series of ferrocene-containing thiazolylpyrazoles – 3-ferrocenyl-2-pyrazolyl-1,3-thiazolidin-4-ones have been synthesized using convenient one-pot three component condensation. Twelve newly synthesized compounds were ...
Synthesis of novel ferrocene-containing 1,3-thiazinan-2-imines: One-pot reaction promoted by ultrasound irradiation
(Tetrahedron Letters, 2018-09)
A simple one-pot synthesis of new ferrocene-containing 1,3-thiazinan-2-imines from 3-arylamino-1-ferrocenylpropan-1-ols and phenyl isothiocyanate has been developed. The key intermediate β-hydroxy thioureas were generated ...

Simulation of chemical accidents with acetylene in 'Messer Tehnogas' Kraljevo plant by 'ALOHA' software program
(The University Thought - Publication in Natural Sciences, 2018)
Chemical plants are generally associated with potentially high risk of chemical accidents. During chemical accidents hazardous substances jeopardize human lives, destroy material assests and degrade natural environment. ...
The Non-Linear Regression - the Levenberg- Marquardt Algorithm for Assumption the Energy Losses of Hydraulic Transport in a Case of the Mine Trepca
(Thermal Science, 2019)
The main problem of hydraulic transport is the resistance generated during the mixture transport through the pipe-line. Testing the flow characteristics of mixtures, shown in this paper, are based on the principles of ...
Synthesis and Electrochemical Estimation of DNA-Binding Capacity of Novel Ferrocene-Containing Pyrrolidines
(The Electrochemical Society, 2020-01)
The design, synthesis, spectral and electrochemical characterization of a series of novel pyrrolidine derivatives have been described. The synthesis was achieved by 1,3-dipolar cycloaddition of azomethine ylides and ...
