Tertiary butyl nitrite (TBN) is an acid-free and safe nitrating agent that provides preferentially -nitrostyrenes with cinnamic acids and corresponding nitro derivatives with phenols in good yields under classical conditions. However, ultrasonic and microwave-assisted reactions reduced the reaction times substantially and enhanced the yields from good to excellent. Supplemental materials are available for this article.
