Book Description
Professor Wilson Baker, F.R.S. Organic compounds are classified as aliphatic, carbocyclic, or heterocyclic, though in the very many cases where two or more such characteristic groupings are present, the classification chosen will depend on the relative chemical importance of these groupings to the particular investigation in hand, and perhaps even to the outlook of the investigator. Traditionally, however, ring compounds with attached aliphatic groups are referred to as cyclic, and any hetero cyclic grouping serves to categorise a molecule as heterocyclic. In these reviews it is the intention to deal, so far as possible, with carbocyclic compounds only, as borne out by this Volume I of the series with articles on the benzidine rearrangement, the bicyclo [3,3,1]nonanes, Feist's acid, and the annulenes. The difficulty in keeping rigidly to carbocyclic substances is, however, apparent in the chapter on 'The Biosynthesis of Carbocyclic Compounds', where many heterocyclic compounds are encountered, as is inevitable in any reasonably comprehensive account of biosynthesis.

Book Description
Cyclo-octatetraene is a compound of fundamental importance to theoretical chemists and has played an outstanding role in many aspects of organic and organometallic chemistry. As [8]annulene, the next higher vinylogue of benzene, it is essential to the understanding of cyclic alternating pi systems. As a medium-ring polyene, it undergoes a wide variety of reactions that are often accompanied by skeletal transformations, and it is the progenitor of a large number of interesting species, ranging in complexity from cyclobutadiene to triamantane. It also forms an exceptional variety of complexes with transition metals, important from the viewpoint of bonding theory, and increasingly useful in providing routes to systems that are not readily available by the conventional transformations of organic chemistry. The recent rapid developments and growth of interest in the study of cyclo-octatetraenes and its derivatives make this comprehensive review especially timely.

Book Description
This book is an attempt to bring together current knowledge on the role and importance of organic acids in life processes. There are lots of compounds based on the chemical nature of this functional group, which makes this class of molecules to be present in our lives starting with the human body (Krebs cycle - the core of cellular metabolism) to the products we currently use (food, medicines and cosmetics). No overall consensus is sought in this book, and the following chapters are authored by dedicated researchers presenting a diversity of applications and hypotheses concerning organic acids. The five chapters in this book include general information on carboxylic acids and their applications in life sciences (use in organic synthesis, nanotechnology, plant physiology, plant nutrition and soil chemistry).

Book Description
The Chemistry of Nonbenzenoid Aromatic Compounds — II is a collection of plenary lectures presented at the Second International Symposium on the Chemistry of Nonbenzenoid Aromatic Compounds. Starting with a review of the synthesis and study of select heterocycles, the book includes results and developments in this area. A significant part of the reviews of nonbenzenoid aromatic compounds is the examination of annulenese that contain larger Huckel systems than benzene. The demand for better synthetic methods in the study has increased as bridged annulenes have been made for suitable models of testing theoretical concepts. Early studies on some nonbenzenoid aromatic compounds and the related problems are also discussed. A description of the syntheses of several polycyclic systems that contain potential cyclobutadiene rings follows. Studies are made on 8-oxoheptafulvene chemistry after earlier chemical and physical examination of heptafulvene and related compounds provided avenues for research. Some aspects of strained systems, [4]annulene and its Ch+adduct are reviewed in terms of usefulness when applying a theoretical guide, proving the calculations and experiments. Studies on higher membered annulenyl ions belonging to five groups are also discussed. Research chemists, students, and professors in chemistry and related fields such as organic chemistry will find this collection useful.
