  • Publication number: 20210017195
    Abstract: A process to functionalize organo-zinc compounds with halosilane electrophiles employs a basic additive. The process includes combining the organo-zinc compound, a halosilanes, and a nitrogen containing heterocycle as the basic additive. The presence of the basic additive facilitates successful substitution. Functionalized silanes and silyl-terminated polyolefins can be prepared using this process. The functionalized silanes may be useful as endblockers for polyorganosiloxanes having SiH and/or silicon bonded aliphatically unsaturated groups capable of undergoing hydrosilylation.

  • Patent number: 9382279
    Abstract: A Cu(I)-catalyzed 1,3-halogen migration reaction effectively recycles an activating group by transferring a halogen from an sp2 to a benzylic carbon with good enantioselectivity and concomitant borylation of the Ar-halo bond. The resulting enantio-enriched benzyl halide can be reacted in the same vessel under a variety of conditions to form an additional carbon-heteroatom or carbon-carbon bond while maintaining high ee. The reaction can be used to efficiently prepare novel compounds and intermediates for the preparation of therapeutics and ligands for catalysis.
