The success of modern organic synthesis mostly relies upon the selection and implementation of proper reagents, which may be either used under specific or variety of conditions. The main purpose of using these reagents is to target the conversion of a specific functional group without affecting the other, a challenging task, and to give higher yields as far as possible. A good reagent must give least problems while working up the reaction.
The qualities of a good reagent suitable for modern organic synthesis are:
Nowadays plenty of reagents for modern organic synthesis are available to the organic chemist to choose among and carry out the reaction smoothly to the desired product on both laboratory and industrial scales.
