Organotransition metal chemistry Subject

Up to 1994 the majority of publications on five-membered monoheterocycles were on phospholes. Since 1995, thiophene has become the ligand of the year. The organotransition metal chemistry of thiophene has been the subject of a substantial number of reviews on its pure and applied chemical... 

Organotransition metal compounds have been known for over a century hut it has been only during the past 15 years that most of the major advances in this area have been made, Organotransition metal compounds consist of organic molecules or ligands coordinated to transition metals by one or more carbon atoms. In the present survey, the formation, properties, structure, and reactions of various classes of these substances are discussed. Emphasis has been placed on important discoveries and theories that have stimulated the rapid progress of organotransition metal chemistry. Pertinent reviews on various aspects of this subject have also been cited. 

Over the last decade, the chemistry of the carbon-carbon triple bond has experienced a vigorous resurgence [1]. Whereas construction of alkyne-con-taining systems had previously been a laborious process, the advent of new synthetic methodology based on organotransition metal complexes has revolutionized the field [2]. Specifically, palladium-catalyzed cross-coupling reactions between alkyne sp-carbon atoms and sp -carbon atoms of arenes and alkenes have allowed for rapid assembly of relatively complex structures [3]. In particular, the preparation of alkyne-rich macrocycles, the subject of this report, has benefited enormously from these recent advances. For the purpose of this review, we Emit the discussion to cychc systems which contain benzene and acetylene moieties only, henceforth referred to as phenylacetylene and phenyldiacetylene macrocycles (PAMs and PDMs, respectively). Not only have a wide... 

A variety of reviews is available on the subject of (7-bonded, organotransition metal compounds. The most recent of these (1965) is a detailed review by Razuvaev and Latyaeva 209) which has recently been translated from the original Russian text. As mentioned earlier, the review by Cotton 63) comprehensively and critically covers the literature up to 1955. Several other reviews, by Coates and Clocking 46) and by Chatt 28, 30), appeared in 1960. The specific area of fluorocarbon-transition metal chemistry has been covered in recent reviews by Clark 4I) in 1963, Treichel and Stone 236) in 1964, and Rausch 203) in 1966.
