Dissertation objectives: - The synthesis of 4-aryl-1-(phenylthio)pyrrolo[1,2-a]quinoxalines through the C-S coupling reaction between 4-arylpyrrolo[1,2-a]quinoxalines and aryl disulfides. - The synthesis of 4-aryl-1-(phenylsulfonyl)pyrrolo[1,2-a]quinoxalines through the C-S coupling reaction between 4-arylpyrrolo[1,2-a]quinoxalines and sodium arylsulfinates. - The optimization of the conditions for both reactions.
- The investigation of the substrate scope for both reactions. - The proposal of plausible mechanisms for both reactions. Start date: 16th February, 2023 4. Finish date: 10th December, 2023 5.
Phan Thanh Son Nam; Dr. Nguyen Thanh Tung Ho Chi Minh City, January 2024 SUPERVISOR 1 SUPERVISOR 2 HEAD OF DEPARTMENT DEAN OF FACULTY OF CHEMICAL ENGINEERING i ACKNOWLEDGEMENT My master’s thesis marks one of the most significant milestones in my academic journey, representing my endless effort in more than two years to achieve a fruitful outcome – a Master’s degree at HCMUT, VNU-HCM. However, I could have not completed it without the support and care of my supervisors, mentors, teammates, and colleagues. Therefore, I sincerely express my gratitude to those who have contributed to my current achievements.
First of all, I would like to deliver many thanks to VNU-HCM Key Laboratory of Materials Structure Analysis (MANAR), Ho Chi Minh City University of Technology, VNU-HCM for creating such precious opportunities for me to take my thesis project. Most importantly, I would like to express my sincerest gratitude to my supervisors, Dr. Nguyen Thanh Tung and Prof. Phan Thanh Son Nam, who always wholeheartedly supported me not only in terms of academic issues but also with thoughtful encouragement.
Moreover, I would also like to send my thankfulness to MSc. Le Xuan Huy, a kind and passionate mentor, who is always ready to answer my chemistry questions. More than knowledge, the “things” you lay in me were the positive change in awareness, skills as well as heartfelt appreciation. Although there were countless moments for me to feel grateful about during the thesis period, the occasion to know and work with my team was the most priceless.
Thanks to you all, Thien Son, Hoang Huy, Nhu Y, Thu Ha, Thai Quyen, Van Phu, and Thuy Ca, my journey was full of memorial stories. Each member left in me deep impressions with a very special sensation. Last but not least, I would like to say my biggest thanks to my family, who always supported me in various aspects and was my most reliable foundation.
