BCl3 hydrolyzes readily to give hydrochloric acid and boric acid: :BCl3 + 3 H2O → B(OH)3 + 3 HCl Alcohols behave analogously giving the borate esters, e.g. trimethyl borate. Ammonia forms a Lewis adduct with<unk> . As a strong Lewis acid, BCl3 forms adducts with tertiary amines, phosphines, ethers, thioethers, and halide ions. Adduct formation is often accompanied by an increase in B-Cl bond length. BCl3•S(CH3)2 (CAS# 5523-19-3) is often employed as a conveniently handled source of BCl3 because this solid (m.p. 88-90 °C) releases BCl3: :(CH3)2S·BCl3 ⇌ (CH3)2S + BCl3 The mixed aryl and alkyl<unk>  chlorides are also of known. Phenylboron dichloride is commercially available. Such species can be prepared by the redistribution reaction of BCl3 with organotin reagents: :2 BCl3 + R4Sn → 2 RBCl2 + R2SnCl2 Reduction Reduction of BCl3 to elemental<unk>  is conduct commercially (see below). In the laboratory, when<unk>  can be converted to diboron tetrachloride by heating with copper metal: :2 BCl3 + 2 Cu → B2Cl4 + 2 CuCl B4Cl4 can also be prepared in this way. Colourless diboron tetrachloride (m.p. -93 °C) is a planar molecule in the solid, (similar to dinitrogen tetroxide, but in the gas phase the structure is staggered. It decomposes at room temperatures to give a series of monochlorides having the general formula (BCl)n, in which n may be 8, 9, 10, or 11. The compounds with formulas B8Cl8 and B9Cl9 are known to contain closed cages of<unk>  atoms.
