OFFERED PROGRAMS

 

Research activities:

 

- Synthesis and 1H, 13C and 19F NMR and IR spectral studies of N- and ring--alkyl substituted anilines and their p-fluoro derivatives. Evaluation of the electron donor strength of amino substituents

- Synthesis of 1-alkyl-4-(4-aminostyryl)pyyridinium salts. 1H, 13C and 15N NMR and UV-Vis spectral studies of intramolecular charge-transfer

- Tautomerism of 2-phenacylquinolines by 1H, 13C, 15N and 17O NMR methods

- Correlation analysis of physico-chemical data of compounds disclosed

 

1. Selected lectures for the advanced students are offered in English depending on the time of the visit and according to the interest of the visitors. The topics are:

- NMR spectra and structure of organic compounds

- Correlation analysis of NMR and UV-Vis spectarl data

- Electronic and steric effects in organic compounds

- Synthesis of selected groups of organic compounds, e.g. pyridines, unusual anilines

2. Faculty of Chemical technology and Engineering at the Academy of Technology and Agriculture in Bydgoszcz is going to receive a limited number of graduate students to work for two months as synthetic and physical chemists. We can help in syntheses of numerous more and less sophisticated benzene a pyridine derivatives. Of course, when working in Bydgoszcz visitors may prepare other compounds they need to solve their problems.

Physical measurements that can be performed in our University refer mainly to 1H and 13C NMR, IR and UV-Vis spectroscopy.

3. Faculty of Chemical Technology and Engineering at the Academy of Technology and Afgriculture in Bydgoszcz offers the following main facilities:

- NMR spectrometer (Varian GEMINI 2000)

- IR spectrophotometer (Bruker VECTOR 22)

- UV-Vis spectrophptpmeter (Varian CARY 3E)

 

The proposed lectures prepared to give when visiting the Partner Institutions are as follows:

- Synthesis of viicinally substituted nitropyridines and their 1-oxides.

- Spectrposcopic studies of the steric effect in aromatic Schiff bases and their aza analogs.

- Electron impact induced framgmenntation of nitropyridines.

- 1-Aminopyridinium satls and related compounds.

- Multinuclear magnetic resonance and X-ray studies of nitraminopyridines.

- Synthesis of p-aminobenzylidene derivatives of the ester, amide and nitrile of p-aminocinnamic acid to be used as the spectroscopic sounds in polymeric materials. The TICT (Twisted Intramolecular Charge Transfer) states of the said compounds by spectral (UV-Vis and fluorimetric) methods are considered to be studied.

- Synthesis of 1-alkyl-4-(4-aminophenyl)pyriidinium salts which are important due to their similarity with some biologically active compounds. Intramolecular charge transfer and conformation of the salts will be studied by spectroscopic methods.

- Synthesis of 2-phenacylquinoline derivatives. The compounds will be studied by multinuclear NMR methods (1H, 13C, 15N and 17O) to discover their tautomerism.

- Correlation analysis of physico-chemical data of the series of compounds discussed above. Other series of aromatic and heteroaromatic derivatives, e.g. ring substituted N-phenylglycines, will be studied too.


Dear Professor Fabian, Thank you very much for your letter of November 12. We have the home page in the Internet but it is written in Polish only and the problems we are working on are there not explained in details. Sorry for that. In our Department we have three pure chemical groups: organic, physical and inorganic. My scientific interest covers the following topics: organic and physical organic chemistry, spectroscopy and correlation analysis in chemistry. We are interested in studying the structures of organic compounds mainly by spectroscopic methods (multinuclear magnetic resonance, UV-visible, MS and IR). This includes mainly tautomerism of some pyridine derivatives and transmission of substituent effect in aromatic compounds. Our recent efforts here are directed to evaluation of tautomeric equilibria of 2-phenacylquinolines that carry different substituents in the phenacyl fragment of the molecule, and to elucidation of the substituent effect of the strong electron-donor amino groups in some aniline derivatives. We have a Varian-Gemini spectrometer (200 MHz), a Bruker IR and a Varian UV-vis spectrophotometers. However, our efforts are focussed mainly to synthesis of the compounds to be studied and to analysis of the spectroscopic data obtained for the compounds we prepared, from other chemists we are cooperating with. Thus, we have good cooperation with Prof. Erkki Kolehmainen (University of Jyvaskyla, Finland) and with Prof. Alexander Perjessy (University of Bratislava, Slovakia). Prof. Kolehmainen has a very good Bruker NMR spectrometer (500 MHz), he is an expert in NMR spectroscopy and his studies are very sophisticated, so the results obtained from him are usually very exciting. The group of Prof. Jerzy Paczkowski (Physical Chemistry) in our Department is working on photoinitiated polymerization, polymeric/spectroscopic probes and dyeing photoinitiators (processes going via photoinitiated electron transfer mechanism). They have two lasers and spectrofluorometer (Hitachi). Poeples working in inorganic chemistry group are rather passive, so it is difficult to say what they are working on. I hope, you will find helpful the above explanation. The working conditions in Poland are not as good as in Austria but if someone in Graz is interested in working in Bydgoszcz, I and Prof. Paczkowski are open to this kind of activity. I am expecting that Borys Osmialowski, who is going to come to Graz in June, 1999, could learn about using the theoretical methods to predict the tautomeric preferences for compounds he has prepared (phenacylquinolines).
