  The reduction of organic halides with tributyltin hydride in the presence of a catalytic amount of triethylborane has been studied. (1) Alkyl iodides and alkyl bromides reacted easily with tin hydride at −78°C to give the corresponding hydrocarbons, while alkyl chlorides were sluggish to react and recovered unchanged. (2) The reduction of alkenyl halides such as 1-deuterio-1-iodo-1-dodecene and 1-

  Rhodium-catalyzed hydrosilylation of alkynes in an aqueous micellar system has been developed. A combination of [RhCl(nbd)](2) and bis(diphenylphosphino)propane (dppp) effects (E)-selective hydrosilylation in the presence of sodium dodecyl sulfate (SDS) in water. The (E)selectivity strongly indicates the formation of a cationic rhodium species via dissociation of the Rh-Cl bond by the action of anionic micelles. The addition of sodium iodide provided (Z)-alkenylsilanes predominantly.

  Lewis acids such as AlCl3 or EtAlCl2 dramatically catalyzed the hydrosilylation of alkynes 1 with trialkylsilanes to produce the corresponding cis-vinylsilanes 2 in a regio- and trans-stereoselective manner. For example, the hydrosilylation of 1-dodecyne la with triethylsilane in the presence of 0.2 equiv of AlCl3 gave cis-1-(triethylsilyl)-1-dodecene in 93% yield. Other alkyl- and phenyl-substituted terminal and internal acetylenes also underwent trans-hydrosilylation very smoothly. In the case of alkoxy- or silyloxy-substituted acetylenes, the use of 1.2 equiv of AlCl3 or EtAlCl2 was essential to obtain the corresponding trans-hydrosilylation products in high yields. Moreover, AlCl3 catalyzed the hydrosilylation of aromatic allenes 11, producing the alkenylsilanes 12 with high regio- and stereoselectivities in moderate to high chemical yields. Not only the simple monosubstituted, but also the disubstituted and trisubstituted allenes, underwent the hydrosilylation reaction smoothly, serving as a useful tool for the synthesis of differently substituted vinylsilanes which are not easily available through the previously known methodologies. The mechanisms for these catalytic reactions of alkynes and allenes are proposed.
