Indole Functionalization via Photoredox Gold Catalysis

22-May-2015 | Sherif J. Kaldas; Alexandre Cannillo; Terry McCallum; Louis Barriault, Organic Letters, 2015

The use of photoredox catalyst [Au2(dppm)2]Cl2 to initiate free-radical cyclizations onto indoles is reported. Excitation of the dimeric Au(I) photocatalyst for the reduction of unactivated bromoalkanes and bromoarenes is used for the generation of carbon-centered radicals. Previous to this work, ...

Palladium-Catalyzed Regioselective Decarboxylative Alkylation of Arenes and Heteroarenes with Aliphatic Carboxylic Acids

22-May-2015 | Chanchal Premi; Ankit Dixit; Nidhi Jain, Organic Letters, 2015

Organic Letters DOI: 10.1021/acs.orglett.5b00878


Fluoride-Assisted Activation of Calcium Carbide: A Simple Method for the Ethynylation of Aldehydes and Ketones

22-May-2015 | Abolfazl Hosseini; Daniel Seidel; Andreas Miska; Peter R. Schreiner, Organic Letters, 2015

The fluoride-assisted ethynylation of ketones and aldehydes is described using commercially available calcium carbide with typically 5 mol % of TBAF·3H2O as the catalyst in DMSO. Activation of calcium carbide by fluoride is thought to generate an acetylide “ate”-complex that readily adds to ...
