Controlling the Regioselectivity of the Hydrosilylation Reaction in Carbon Nanoreactors

open access: yesChemistry - A European Journal, 2012
Hollow graphitized carbon nanofibres (GNF) are employed as nanoscale reaction vessels for the hydrosilylation of alkynes. The effects of confinement in GNF on the regioselectivity of addition to triple carbon–carbon bonds are explored.

Ziegler–Natta Catalysts: Regioselectivity and “Hydrogen Response”

open access: yesACS Catalysis, 2020
Advanced High Throughput Experimentation (HTE) methods were applied to quantify the regioselectivity and the so-called "hydrogen response" in propene polymerization of four Ziegler-Natta catalysts representative of the three latest industrial generations

Regioselective Allylzincation of Alkenylboronate

Organic Letters, 2001
[reaction: see text] Boryl substitution on an olefin activates the olefinic double bond toward addition of an organozinc reagent. Addition of an allylic zinc reagent to an alkenylboronate thus takes place smoothly to afford a variety of gem-zincio/boryl species.

Regioselective Difunctionalization and Annulation of Ynamide

Angewandte Chemie, 2023
AbstractThe use of ynamides in organic synthesis has gained significant attention due to their ability to provide access to complex molecular structures through transformations such as 1,2‐difunctionalization and annulation reactions. These reactions enable the formation of highly functionalized N‐bearing olefins and unusual N‐bearing heterocycles.

Regioselectivity in the Nitration of Dialkoxybenzenes

The Journal of Organic Chemistry, 2011
Dinitrodialkoxybenzene derivatives are important precursors for Schiff base macrocycles and a variety of other molecules. During our investigations, we have found that the dinitration reaction of 1,2-dialkoxybenzenes proceeds with unusual regioselectivity, giving exclusively the desired 1,2-dialkoxy-4,5-dinitrobenzene product, but we have been unable ...
