  Regioselective hydrostannation of highly hindered arylalkynes under ortho-directing effects

  摘要：

  Palladium-catalyzed hydrostannation reactions of ortho-disubstituted arylalkynes were achieved with total stereo- and regio-selectivity in THF at room temperature. The regioselectivity was found to be under the control of the ortho-substituents (ortho-directing effects. ODE) and pure alpha-vinylstannanes are produced in good yields and as single isomers regardless of the substituents' nature. These hydrostannation alpha-products are precursors of choice for the preparation of stereo-defined triarylolefins. (C) 2010 Elsevier Ltd. All rights reserved.
