摘要

The discipline of organic free radical chemistry dates back over 110 years since the discovery oftriphenylmethyl radical by Moses Gomberg in 1900.Organic radical reactions became a thriving field in synthetic organic chemistry for a decade or so starting from the mid 1980s.Nevertheless,the significance of radicals in organic synthesis somehow re mained hidden for a long period of time.The 1990s saw a renaissance of stereoselective radical reactions once deemed unattainable.The turn of the 20th century led to the development of new ways to carry out stereoselective radical reactions using organocatalysts.In the past decade,we have witnessed new directions for organic radical chemistry.It has now become an exciting area of research in organic chemistry,and new discoveries can be seen every day in various aspects of radical chemistry such as photoredox catalysis,transition-metal-catalyzed radical reactions,and application of electrochemistry.Besides the advances in new methodologies,the past decades have led to the development of a large tool box of reagents and catalysts to carry out radical reactions efficiently and selectively with an eye to meet the 21st century metrics of low toxicity,minimal waste,green solvents,and sustainability.
