Abstract: A process is described in which catecholborane is produced by a reaction of a phenolic compound with a boron hydride in a solvent. Tris(catecholato)bisborane, i.e. the ester of boric acid and catechol, is reacted with an alkali metal-boron hydride in an aliphatic ether. A lithium halide is suitably used too, where sodium-boron hydride or potassium-boron hydride is employed. In a preferred embodiment, the reaction is carried out in conjunction with an activating grinding operation.

Abstract: In a process for hydroboronizing alkenes or alkynes with catecholborane (1,3,2-benzodioxaborolane) optionally in the presence of an added organic solvent the reaction is catalyzed by a complex compound having one of the formulas:(I) RhCl(CO).sub.x [E(C.sub.6 H.sub.5).sub.3 ].sub.3-x' wherein "E" is arsenic or phosphorous and "x" equals 0 or 1,(II) [RhCl(alkene).sub.2 ].sub.2'(III) [(C.sub.6 H.sub.5).sub.3 P].sub.3 3 Ru(CO)ClH or(IV) [(C.sub.6 H.sub.5).sub.3 P].sub.3 RuCl.sub.2,particularly suitable catalysts are, e.g. tris (triphenylphosphine)rhodium(I) chloride and bis(cyclooctadiene)rhodium(I) chloride.

Abstract: Esters of .alpha.,.alpha.-haloalkyl boronic acids are prepared by the addition of an alkali metal dialkylamide, or some other equivalent sterically hindered base to a mixture of a 1,1-dihaloalkane and a trialkyl borate in an organic solvent at a temperature between about -78.degree. C. and +25.degree. C. In one embodiment, diisopropyl (dichloromethyl)borate is formed by the addition of lithium diisopropylamide to a mixture of dichloromethane and triisopropyl borate in the presence of tetrahydrofuran as the solvent medium at a temperature between about -10.degree. C. and +10.degree. C.
