 Hello everyone, my name is Yashwant D. Vankar, I was a professor of chemistry at IIT Kanpur since 1981 and retired in 2018 and then I have moved to Mumbai. The course that I am going to offer is titled Essentials of Oxidation Reduction and C-C-Bond Formation Application in Organic Synthesis. As I am recording the lectures of this course at IIT Bombay, therefore from now on my association is also with IIT Bombay. I am grateful to the in-charge NPTEL and all the team members of NPTEL at IIT Bombay to allow me to record these lectures. I will be assisted by Dr. Padma S. Vankar as the teaching assistant in this course. This course is actually primarily meant for students who have some ideas of organic reactions at the B.Sc level and are now studying for M.Sc degrees and also they are planning to appear for exams not only for their M.Sc degrees but also for say NET, GATE and GRE examinations. The course that I am dealing with will involve various aspects of oxidation reduction and C-C-Bond formations and also some rearrangements especially with the emphasis on mechanism, stereochemistry and selectivity including enantioselectivity. As you all know that the importance of chiral molecules in terms of their utilization in drugs is very, very important. So there will be some emphasis on enantioselectivity also. These are essentials and not exhaustive methods. Now on the basis of the experience that I have for the past several years more than 37 years at IIT Kanpur I have selected a few important oxidation reduction and C-C-Bond forming reactions and that is what I am going to discuss in this particular course. I expect that this course will therefore be useful not only from the examination point of view that I mentioned but also perhaps it will help to make a foundation for research in future. I will be giving assignments from time to time and of course there will be an examination at the end of the course. Of course at the same time we will have ample opportunities to interact with you online. I am now looking forward to interact with you all during this course. See you soon. Till then bye.
