Use of transition organometallic compounds

Chapter 12 serves as an introduction to a huge area of chemistry devoted to the use of organometallic compounds for the construction of complex molecules. The material covered in Chapter 12 exemplifies several of the most important applications of organotransition metal chemistry to organic synthesis. Thousands of articles have appeared over the past 10 years that report on either the use of transition metal compounds in key steps of syntheses, which would be difficult or even impossible to carry out without transition metals, or on the development of novel methodology that may have many applications to synthesis down the road. Research on the connection between organometallic chemistry and synthesis remains active and fruitful, and there is every indication that this endeavor will continue to hold the interest of chemists for many years to come. 

Carbon-carbon bond formation is the most important reaction in synthetic organic chemistry. Various carbon sources can be utilized for the construction of carbon skeletons. Carbon dioxide (C02) is a nontoxic, cheap, and attractive Ci-source.1,la ld The incorporation of C02 into organic compounds can be achieved by use of various organometallic reagents or catalysts, especially those of transition metals.2 2a 2d This chapter focuses on the carbon-carbon bond formation reactions between C02 and acetylenes and dienes, and covers literature from 1993 to 2004. Subsections are categorized according to metals.
