The purpose of this study was to develop a new technology for preparing mercury-free metallic dental restorative materials. The novel approach relies on the cold welding of surface treated silver particles. At ambient temperature, intermetallic compound formation takes place spontaneously

A novel series of alkyne-containing potassium organotrifluoroborates were prepared in good yields from the corresponding haloaryltrifluoroborates and various alkynes via Sonogashira coupling reaction. Also, the Suzuki-Miyaura cross-coupling reaction of alkynylaryltrifluoroborates with aryl and alkenyl bromides was achieved in the presence
