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

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
