Room-Temperature Suzuki−Miyaura Couplings in Water Facilitated by Nonionic Amphiphiles
摘要:
Use of a dilute aqueous solution containing a nonionic amphiphile allows efficient Suzuki-Miyaura cross-couplings of arylboronic acids with a wide array of aryl halides and pseudohalides, including sterically hindered and lipophilic substrates, in most cases at room temperature.

Deprotonative Silylation of Aromatic C–H Bonds Mediated by a Combination of Trifluoromethyltrialkylsilane and Fluoride
method for the deprotonative silylation of aromatic C–H bonds has been developed using trifluoromethyltrimethylsilane (CF3SiMe3, Ruppert–Prakash reagent) and a catalytic amount of fluoride. In this reaction, CF3SiMe3 is considered to act as a base and a silicon electrophile. This process is highly tolerant to various functional groups on heteroarenes and benzenes. Furthermore, this method can be applied
