  Olefin cross-metathesis/Suzuki–Miyaura reactions on vinylphenylboronic acid pinacol esters

  摘要：

  A series of alkenyl phenylboronic acid pinacol esters has been synthesized via an olefin cross-metathesis reaction of vinylphenylboronic acid pinacol ester derivatives. After catalytic hydrogenation, the resulting boronates were coupled via a microwave-mediated Suzuki-Miyaura reaction to afford a library of biarylethyl aryl and biarylethyl cycloalkyl derivatives. A complementary reaction sequence involved an initial Suzuki-Miyaura coupling. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.

• Alkyne Semihydrogenation with a Well-Defined Nonclassical Co–H₂ Catalyst: A H₂ Spin on Isomerization and <i>E</i>-Selectivity

  The reactivity of a co(I)-H-2 complex was extended toward the semihydrogenation of internal alkynes. Under ambient temperatures and moderate pressures of H-2, a broad scope of alkynes were semihydrogenated using a Co-I-N-2 precatalyst, resulting in the formation of trans-alkene products. Furthermore, mechanistic studies using H-1, H-2, and parahydrogen induced polarization (PHIP) transfer NMR spectroscopy revealed cis -hydrogenation of the alkyne occurs first. The Co-mediated alkene isomerization afforded the E-selective products from a broad group of alkynes with good yields and E/Z selectivity.
