As a strong Lewis acid, BCl 3 forms adducts with tertiary amines, phosphines, ethers, thioethers, and halide ions. [5] Adduct formation is often accompanied by an increase in B-Cl bond length. BCl 3 •S(CH 3) 2 (CAS# 5523-19-3) is often employed as a conveniently handled source of BCl 3 because this solid (m.p. 88-90 °C) releases BCl 3:

Most compounds considered to be Lewis acids require an activation step prior to formation of the adduct with the Lewis base. Complex compounds such as Et 3 Al 2 Cl 3 and AlCl 3 are treated as trigonal planar Lewis acids but exist as aggregates and polymers that must be degraded by the Lewis base. [10] A simpler case is the formation of adducts ...
Experimental equilibrium measurements, its AN value (Gutmann-Beckett method) as well as quantum-chemical calculations all indicate that the Lewis acidity of B(C 6 F 5) 3 is slightly lower than that of BF 3 and significantly reduced compared to BCl 3. B(C 6 F 5) 3 forms a strong Lewis adduct with water, [5] which was shown to be a strong ...
BF 3 + BCl 3 → BF 2 Cl + BCl 2 F. Because of the facility of this exchange process, the mixed halides cannot be obtained in pure form. Boron trifluoride is a versatile Lewis acid that forms adducts with such Lewis bases as fluoride and ethers: CsF + BF 3 → Cs[BF 4] O(CH 2 CH 3) 2 + BF 3 → BF 3 ·O(CH 2 CH 3) 2
The first synthesis of a tetrahalodiborane was reported by Stock et al. in 1925 where the authors reduced BCl 3 to form B 2 Cl 4 by running a current between zinc electrodes immersed in liquid BCl 3. [1] Later work explored gas phase syntheses of B 2 Cl 4 using gaseous BCl 3 and mercury electrodes. [7]
Triphenylborane, often abbreviated to BPh 3 where Ph is the phenyl group C 6 H − 5 , is a chemical compound with the formula B(C 6 H 5 ) 3 . It is a white crystalline solid and is both air and moisture sensitive, slowly forming benzene and triphenylboroxine .
Lanthanide trichloride, LnCl 3, a class of chemical compound composed of a lanthanide atom and three chloride atoms. Lawrencium trichloride , LrCl 3 , a compound synthesised in 1969 expected to follow other actinide trichlorides.
