  • Patent number: 4739096
    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.

  • Patent number: 4731463
    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.
