A general copper-catalyzedC(sp3)−C(sp2) cross-coupling of (hetero)benzyl bromides with the air- and moisture-stable aryl nucleophiles has been developed, providing a facile access to pharmaceutically useful 1,1-di(hetero)arylalkane and 1-aryl-1-heteroarylalkane scaffolds. Critical to the success is the utilization of a proline-based N,N,P-ligand to enhance the reducing capability of copper, thus easily
We herein report the development of a regioselective synthetic route to [70]methanofullerenes, which have potential for application as electron acceptors in solution-processed bulkheterojunctionsolarcells. Sterically hindered sulfur ylide, generated in situ from their corresponding sulfonium salts in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the base, smoothly reacted with [70]fullerene
[6,6]-Phenyl C71 butyric acid derivatives (C70-PCBR3) having a selectivity of greater than 95 wt % of the α-isomer are provided by reacting fullerene C70 with a dialkyl sulfonium tetrafluoroborate having the formula:
[reaction: see text] Aryl- and alkyl-derived azidoacyl radicals, generated from thiolesters by intramolecular homolytic substitution at the sulfur, can undergo five- and six-membered cyclizationonto the azido moiety to give cyclized lactams.
