Regioselective modification of unprotected glycosides.
Regioselective modification of unprotected glycosides.
Chem Commun (Camb). 2015 Nov 16;
Authors: Jäger M, Minnaard AJ
Abstract
Selective modification of unprotected carbohydrates is difficult due to the similar reactivity of the hydroxyl groups. In carbohydrate synthesis, therefore, even straightforward transformations often require multiple synthetic steps. The development of selective methods for carbohydrate modification is consequently highly desired. This review describes the methods for the regio- and chemoselective carbohydrate modification, with a focus on novel approaches that mainly apply transition metal catalysis and organocatalysis, and discusses the challenges and opportunities in this field.

Heat-induced formation of one-dimensional coordination polymers on Au(111): an STM study.
Chem Commun (Camb). 2015 Aug 17;
Authors: Pham TA, Song F, Alberti MN, Nguyen MT, Trapp N, Thilgen C, Diederich F, Stöhr M
Abstract
The formation of one-dimensional coordination polymers of cyano-substituted porphyrin derivatives on Au(111) induced by thermal annealing is demonstrated by means of scanning tunnelling microscopy. The polymer is stabilised by an unusual threefold coordination motif mediated between an Au atom and the cyano groups of the porphyrin derivatives.

Catalyst-controlled reverse selectivity in C-C bond formation: NHC-Cu-catalyzed α-selective allylic alkylation with organolithium reagents.
Catalyst-controlled reverse selectivity in C-C bond formation: NHC-Cu-catalyzed α-selective allylic alkylation with organolithium reagents.
Chem Commun (Camb). 2015 Apr 15;
Authors: Pizzolato SF, Giannerini M, Bos PH, Fañanás-Mastral M, Feringa BL
Abstract
An efficient and highly α-selective copper-catalyzed allylic alkylation of allylic halides with organolithium reagents is presented. The use of N-heterocyclic carbenes as ligands is key to reverse the common γ-selectivity of this transformation and gives rise to the corresponding linear products with high levels of regioselectivity.

Fullerene derivatives with increased dielectric constants.
Chem Commun (Camb). 2014 Jul 30;
Authors: Jahani F, Torabi S, Chiechi RC, Koster LJ, Hummelen JC
Abstract
The invention of new organic materials with high dielectric constants is of extreme importance for the development of organic-based devices such as organic solar cells. We report on a synthetic way to increase the dielectric constant of fullerene derivatives. It is demonstrated that introducing triethylene glycol monoethyl ether (teg) side chains into fulleropyrrolidines increases the dielectric constant by ∼46 percent without devaluation of optical properties, electron mobility and the energy level of the compound.

Abstract
The adsorption behaviour as well as the influence of bromine substituents on the formation of highly-ordered two-dimensional structures of pyrene derivatives on Au(111) are studied by a combination of scanning tunnelling microscopy (STM) and density functional theory (DFT) calculations.
