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

The protonation of the phosphinito-bridged Pt(I) complex [(PHCy(2))Pt(μ-PCy(2)){κ(2)P,O-μ-P(O)Cy(2)}Pt(PHCy(2))](Pt-Pt) (1) by aqueous HBF(4) or hydrofluoric acid leads selectively to the hydrido-bridged solvento species syn-[(PHCy(2))(H(2)O)Pt(μ-PCy(2))(μ-H)Pt(PHCy(2)){κP-P(OH)Cy(2)}](Y)(2)(Pt-Pt) ([2-H(2)O]Y(2)) {Y = BF(4), F(HF)(n)} when an excess of acid was used. On standing in halogenated solvents

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

Organic letters, 12(21), 4876-4879 (2010-10-01)
Amidomethyltrifluoroborates were successfully synthesized in a one-pot fashion and used in cross-coupling reactions with a wide variety of aryl and heteroaryl chlorides.

The Analyst, 125(12), 2285-2288 (2001-02-24)
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
