TRANSITION METAL COMPLEXES AS CATALYST FOR ORGANIC REACTION ABSTRACT Transition metal complexes as catalyst for organic reaction. As pointed out earlier, this review gives an overview of some of the catalytic reactions that are useful, either on a laboratory sale or industrial scale of certain organic compounds. No attempt has been made to include all the catalytic reactions in which transition metal complexes are involved. Research has come a long way from the time of Werner and Jorgenesen, in terms of the growth that coordination Chemistry has experienced over the last few decades. Their work was stepping stone for the development of modern inorganic Chemistry which is truly a multidisciplinary one in the present day context. The ever increasing importance of metal complex analyzed reactions has already been discussed above. CHAPTER ONE INTRODUCTION The study of coordination chemistry in the modern day context began with two notable scientists, (Alfred werner nor 2002) and sophus mads Jorgensen. Although there was considerable controversy between werner and jorgensen regarding the interpretation of their experimental results on the structures of coordination compounds, one cam now conclude that werner’s interpretation of his results is correct;. The (pioneering 19992) contribution of Werner to the study of coordination chemistry fetched him the Nobel prize in chemistry in 1913 and incidentally he is the first organic chemistry to win the coveted distinction. Despite jorgensen’s interpretation being ‘ wrong’ his contributions by no means are to be ignored. As chemists we owe a lot to these two people who contributed immensely to our understanding of the chemistry of coordination compounds. The details of the contributions of Werner and jorgensen are out of scope of this review. Soon after the reports by (Werner 2002) and (jorgensen 2006) there have been different approaches towards the study of bonding in transition metal complexes. Despite rigorous study, there still exist Laurence in the understanding of reaction mechanisms in the case of inorganic chemistry compared organic chemistry. This lack of understanding of reaction, mechanisms spills over into synthesis as well to a certain extent. Synthetic tricks are sometimes discovered that allow one to prepare a desired compound without the interference from an undesired product. Werner discovered that certain cis isomers could be prepared, from a carbonate compounds that would react with acid to generate carbon dioxide and insert two anions of the acid as ligands. The purpose review is to highlight some of the applications of transition metal compounds as catalysts, The subject matter of this review will consist of certain general principles outlining the features involved for a transition metal complex to act as a catalytis, reactions some specific catalytic reactions that are being employed in industry currently,briefly some comments on industry academia collaborations current and future trends in catalysis, and finally conclusion.
