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
Amidomethyltrifluoroborates were successfully synthesized in a one-pot fashion and used in cross-coupling reactions with a wide variety of aryl and heteroaryl chlorides.
Several mu-oxo-bismetalloporphyrin complexes were synthesized for preparing fluoroborate sensors. The electrode based on mu-oxo-bis[tetra(p-chlorophenyl)porphinatomanganese(III)] with an optimized membrane composition shows a potentiometric response towards fluoroborate ion over the concentration range from 4.3 x 10(-7) to 1.0 x 10(-1) mol l-1

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 colloidal solution is a homogeneous dispersion of particles or droplets of one phase (solute) in a second, typically liquid, phase (solvent). Colloids are ubiquitous in biological, chemical and technological processes, homogenizing highly dissimilar constituents. To stabilize a colloidal system
