The Organic Chemists' Companion provides a practical, hands-on resource for students and practitioners of organic synthesis. The book presents the fundamentals and guides the reader through the entire process of organic synthesis. It includes basic instructions on everything from on handling reagents, gases, and solvents to conducting and working up/purifying reactions as well as applying analytical techniques to identify the reaction product.
