Chiara Fasciani, Carlos J. Bueno Alejo, Michel Grenier, Jose Carlos Netto-Ferreira, and J. C. Scaiano, “High-Temperature Organic Reactions at Room Temperature Using Plasmon Excitation: Decomposition of Dicumyl Peroxide”, Org. Lett.13 (2), 204-207 (2011), Dec. 2010.

Decomposition of Dicumyl Peroxide
Photoexcitation of gold nanoparticles in their plasmon transition around 530 nm provides the means to carry high-energy reactions at room temperature. In the case of dicumyl peroxide (with activation energy of 34.3 kcal/mol) the reaction occurs in less than 1 min under 532 nm laser excitation. The results suggest that the peroxide is exposed to temperatures of 223C500 °C for submicrosecond times, and provides a guide as to which type of organic reactions may benefit from plasmon-mediated energy delivery.
