Chemistry of Carbon Compounds : Aromatic Compounds
Part B: Benzoquinones and Related Compounds
Derivatives ... and Phenolic Aralkyl Compounds,
By
Malcolm Sainsbury
Publisher
Elsevier Publishing Company
Number Of Pages: 382
Publication Date: 1995-08-01
ISBN-10 / ASIN: 0444822429
ISBN-13 / EAN: 9780444822420
This volume spans several very important areas of aromatic chemistry. It
includes chapters devoted to benzoquinone, nitro compounds, metallo derivatives
and aromatic hydrocarbons with substituents which contain more than
one nitrogen atom, e.g., azobenzenes, azides, etc.
The first chapter is written by Dr. Malcolm Bruce. It is fitting that I should
recognise Dr. Bruce's special contribution to Rodd, since it was he who wrote
on this subject in the 2nd edition in 1974 and again in the 1st Supplement.
Dr. Bruce's enthusiasm and lifelong interest in this subject is still very evident,
and this can easily be judged by the style with which he has surveyed progress
in benzoquinone chemistry in the last decade.
The application of organometallic chemistry to synthesis has been spectacular,
and two chapters in this volume emphasise this development. With so
much information, the task of condensing the most significant new knowledge
into a readable and informative account is a daunting one. Yet the authors,
Dr. Mullins and Professors Pearson and Woodgate, have managed this with
skill and flair. Dr. Simon Fortt has written on the chemistry of the nitroarenes.
This is a subject steeped in history, but it is still very much alive and relevant
today as is highlighted in Dr. Fortt's contribution.
I would like to thank all the authors for making my job as editor an easy
and intellectually rewarding one.
