Direct arylation catalysis with chloro[8-(dimesitylboryl)quinoline-κN]copper(I)

Autor: Sem Raj Tamang, James D. Hoefelmeyer

Publikováno v: Beilstein Journal of Organic Chemistry, Vol 12, Iss 1, Pp 2757-2762 (2016)

We report direct arylation of arylhalides with unactivated sp2 C–H bonds in benzene and naphthalene using a copper(I) catalyst featuring an ambiphilic ligand, (quinolin-8-yl)dimesitylborane. Direct arylation could be achieved with 0.2 mol % catalys

Chloro({2-[mesityl(quinolin-8-yl-κN)boryl]-3,5-dimethyl-phenyl}methyl-κC)palladium(II) as a Catalyst for Heck Reactions

Autor: Sem Raj Tamang, James D. Hoefelmeyer

Publikováno v: Molecules, Vol 20, Iss 7, Pp 12979-12991 (2015)

We recently reported an air and moisture stable 16-electron borapalladacycle formed upon combination of 8-quinolyldimesitylborane with bis(benzonitrile)dichloropalladium(II). The complex features a tucked mesityl group formed upon metalation of an or

Crystal structure of 8-iodoquinolinium tetrachloridoaurate(III)

Autor: Benard O. Onserio, Sem Raj Tamang, James D. Hoefelmeyer

Publikováno v: Acta Crystallographica Section E: Crystallographic Communications, Vol 71, Iss 12, Pp m261-m262 (2015)

The structure of the title salt, (C9H7IN)[AuCl4], is comprised of planar 8-iodoquinolinium cations (r.m.s. deviation = 0.05 Å) and square-planar tetrachloridoaurate(III) anions. The asymmetric unit contains one 8-iodoquinolinium cation and two halfs
