This book presents a large number of organic reactions performed under green conditions, which were earlier performed using anhydrous conditions and various volatile organic solvents. The conditions used involve green solvents like water, super critical carbon dioxide, ionic liquids, polymer-supported reagents, polyethylene glycol and perfluorous liquids. A number of reactions have been conducted in solid state without using any solvent. Most of the reactions have been conducted under microwave irradiations and sonication. In large number of reactions, catalysts like phase transfer catalysts, crown ethers and biocatalysts have been used. Providing the protocols that every laboratory should adopt, this book elaborates the principles of green chemistry and discusses the planning and preparations required to convert to green laboratory techniques. It includes applications relevant to practicing researchers, students and environmental chemists. This book is useful for students (graduate and postgraduate), researchers and industry professionals in the area of chemical engineering, chemistry and allied fields.

Talks about the lesser known facts and accounts of the intrusions and the war from various commanders and officers, some of whom have also served during the conflict. The book has been divided into five parts. The first part titled, ‘Blood, Guts and Glory,’ briefly discusses the actual battles fought in Dras, Mushkoh, Batalik, Kaksar and Turtuk sub-sectors, to evict the Pakistani intruders from the dominating heights in the Kargil region. The aim was to restore the LoC to its originally held positions. The second part analyses the supporting forces which synergised the effort to victory, in the true spirit of ‘Op Vijay’. In the third part, individual officers, associated with Kargil, have shared their perceptions and opinions about the Kargil conflict and the scenario after 20 years. The fourth part focuses on ‘Motivation;’ and reflects the saga of courage and valour of the Indian Armed Forces, and the junior leadership, during the summer of 1999. The fifth part, ‘Emerging Challenges and the Way Ahead’ looks at the emerging global-cum-regional scenario, the envisaged threats, our preparedness, and makes substantial recommendations to face the conflicts of the future.The forecasts provided by some of the most senior military officers of the country give a sneak peek into the emerging challenges of the future and India’s preparatory responses to them. Given the emerging world order and the revolutionary changes in technology and character of conflicts, the book restates the fundamental focus of the Indian Armed forces: to be prepared to face the envisaged threats and challenges of the future.

Organic chemistry has played a vital role in the development of diverse molecules which are used in medicines, agrochemicals and polymers. Most ofthe chemicals are produced on an industrial scale. The industrial houses adopt a synthesis for a particular molecule which should be cost-effective. No attention is paid to avoid the release of harmful chemicals in the atmosphere, land and sea. During the past decade special emphasis has been made towards green synthesis which circumvents the above problems. Prof. V. K. Ahluwalia and Dr. M. Kidwai have made a sincere effort in this direction. This book discusses the basic principles of green chemistry incorporating the use of green reagents, green catalysts, phase transfer catalysis, green synthesis using microwaves, ultrasound and biocatalysis in detail. Special emphasis is given to liquid phase reactions and organic synthesis in the solid phase. I must congratulate both the authors for their pioneering efforts to write this book. Careful selection of various topics in the book will serve the rightful purpose for the chemistry community and the industrial houses at all levels. PROF.
