Olefin Cyclopropanations via Sequential Atom Transfer Radical Addition-Dechlorination Reactions

Autor: Katrin Thommes, Kay Severin

Publikováno v: CHIMIA, Vol 64, Iss 3 (2010)

In organic synthesis, cyclopropanation reactions are often performed with Simmons–Smith-type reagents or by transition metal catalyzed reactions of olefins with diazo compounds. A novel method for the synthesis of substituted cyclopropanes is descr

Publikováno v: Organometallics. 30:6119-6132

Five different types of β-diketiminate ligands, bearing electron-donating to strongly electron-withdrawing substituents, were synthesized and used in the synthesis of Cp* ruthenium complexes (Cp* = η5-C5Me5). One series consists of complexes with a

Publikováno v: European Journal of Organic Chemistry. 2011:249-255

Sequential intermolecular atom transfer radical addition reactions of activated dichlorides Cl2CRR′ (R = CN, CO2Et, R′ = H, CN, CO2Et) with two olefins catalyzed by [Cp*RuCl2(PPh3)] in the presence Mg allow the synthesis of linear 1,5-dichlorides

ChemInform Abstract: Ruthenium-Catalyzed Synthesis of 1,5-Dichlorides by Sequential Intermolecular Kharasch Reactions

Autor: Rosario Scopelliti, Katrin Thommes, Aurélien Godinat, Charlotte Buron, Kay Severin, Mariano A. Fernandez‐Zumel

Publikováno v: ChemInform. 42

Ruthenium-catalyzed reaction of styrene derivatives (II) with α,α-dichloro-malononitrile, -malonate or -acetonitrile (I) proceeds via a double Kharasch pathway to give symmetrical or unsymmetrical 1,5-diaryl-1,5-dichlorides in good yields.

Ruthenium-Catalyzed Synthesis of 1,5-Dichlorides by Sequential Intermolecular Kharasch Reactions (Eur. J. Org. Chem. 2/2011)

Autor: Mariano A. Fernández-Zúmel, Charlotte Buron, Aurélien Godinat, Katrin Thommes, Kay Severin, Rosario Scopelliti

Publikováno v: European Journal of Organic Chemistry. 2011

The cover picture shows Mariano Fernandez-Zumel taking two steps at the same time. In the laboratory, two-step reactions have been realized in one pot by coupling 1,1-dichlorides with two olefins in sequential atom transfer radical addition (ATRA) re
