Cul-catalyzed coupling reaction of vinylhalides and phenols occurs at 60-90 °C with N,N-dimethylglycine hydrochloride as the additive, giving vinylarylethers in good yields. The cross-coupling products formed from o-iodophenols and vinyl iodides are converted into substituted benzofurans via an intramolecular Heck reaction.
Highly efficient and general Ir-catalyzed hydrosilylation of unactivated alkenes with excellent anti-Markovnikov regioselectivity was described. A broad scope of hydrosilylated products were synthesized economically and conveniently from commercially or naturally available compounds, which provides versatile valuable precursors for organic and medicinal studies.
