 Welcome to this course on Transition Metal Organometallics in Catalysis and Biology. Now, this is a very interesting and exciting area that you would be covering in this transition metal organometallics in catalysis and biology. Particularly, we will be looking at applications of transition metal organometallic compounds in chemical catalysis. Now this is a topic which has been explored a lot in transition metal organometallic chemistry. However, we are going to take up new applications of transition metal organometallics which is bio organometallic chemistry. This is an emerging frontier and this is a part of the area which falls under bio inorganic chemistry. Now this course is mainly to be focused for undergraduates, as well as people in industry who are looking into the applications of organometallic compound. For the course, the books to be covered are Christoph Eisenberg organometallics third edition, Robert Crabtree, G. Simonaix bio organometallic chemistry, and Jared Jocain bio organometallic chemistry applications in drug discovery, bio catalysis and imaging. This course would be beneficial for science undergraduates and postgraduate students, doctoral students interested in synthesis and catalysis as well as engineering students interested in chemical industry. The course will provide a glimpse of the applications that are available to organometallic chemistry. It also provides exciting the domain that lies ahead of the utility of organometallic compounds and which can be observed from the recipient of nine noble prizes in the last century to the field of organometallic chemistry. I hope that this course will provide an elaborate understanding of the subject and the field of applications of organometallic chemistry in catalysis as well as biology. The main primary challenge of organometallic compounds are that they are air and moisture sensitive and hence to synthesize and handle them is a challenge. If the challenge is overcome through proper training and proper application, then this transition metal organometallic chemistry opens door to wonderful set of applications which we would be taking up in this course as we meet in the subsequent lectures. With that, I look forward to being with you in this exciting journey of applications of transition metal organometallics in catalysis and biology. I look forward to very good interaction with you in this advanced level course of organometallic chemistry. Thank you.
