Essentials of Oxidation, Reduction and C-C Bond Formation. Application in Organic Synthesis

By Prof. Yashwant D Vankar   |   IIT Bombay and IISER Thiruvananthapuram
Learners enrolled: 665
In this course I will deal, in detail, of some of the modern and important methods/aspects of
(a) Oxidation
(b) Reduction and
(c) C-C Bond Formation
with special emphasis on addressing
(i) Selectivity [Regio-, Chemo- and Stereo- (Enantio- and Diastereoselectivity)]
(ii) Mechanism
(iii) Stereochemistry (wherever necessary) and
(iv) Application in solving some synthetic problems using the synthetic reactions discussed
Note: (1) I will give appropriate references of books, research papers, and reviews for people for extra information as and when they need. (2) It is expected that this course will help MSc students appearing for NET, GATE and GRE/AGRE examinations. It will also help chemists working in industry who use such reactions in their daily work.

Instructor bio

Prof. Yashwant D Vankar

IIT Bombay and IISER Thiruvananthapuram
1. I am an Emeritus Professor at the School of Chemistry, Indian Institute of Science Education and Research, Thiruvananthapuram (IISER, Thiruvananthapuram) since November 2019. Prior to that I was a Professor of Chemistry at IIT Kanpur since March 1981 to October 2018. 2. Over the years (more than 37 years at IIT Kanpur) I have taught a variety of compulsory and elective courses to Ph. D., M.Sc, and B.Tech students which were well appreciated by the student community. Now, at present also I am teaching organic chemistry at IISER Thiruvananthapuram. 3. Besides getting a number of commendation letters, almost every semester, from the Director of IIT Kanpur for excellent teaching, I was given Distinguished Teachers Award by IIT Kanpur in 2015. 4. I have also been very active in research in organic chemistry. 5. I have guided 41 PhDs, more than 60 MSc research projects, and a few post-doctoral fellows. I have published close to 180 papers in various important international journals. 6. A number of research projects were also funded to me from various funding agencies such as DST, CSIR, MHRD etc. 7. With this rich experience and background, I wish to put in efforts for the benefit of other students/chemists through NPTEL courses.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
