Differential Production of phytotoxins from Phomopsis sp. from grapevine plants showing esca symptoms

Goddard, Mary-Lorène ; Mottier, Nicolas ; Jeanneret-Gris, Julie ; Christen, Danilo ; Tabacchi, Raphaël ; Abou-Mansour, Eliane

In: Journal of Agricultural and Food Chemistry, 2014, vol. 62, no. 34, p. 8602–8607

Nine strains of the fungus Phomopsis spp. were isolated from a vineyard showing decline from the disease esca. Strains were screened for their ability to produce secondary metabolites showing chemical diversity. The culture extracts of each strain were analyzed by liquid chromatography–ultraviolet–diode array detection–mass spectrometry. Three strains were selected for the isolation and...

Ruthenium(II) complexes with ferrocene-modified arene ligands: synthesis and electrochemistry

Therrien, Bruno ; Vieille-Petit, Ludovic ; Jeanneret-Gris, Julie ; Štěpnička, Petr ; Süss-Fink, Georg

In: Journal of Organometallic Chemistry, 2004, vol. 689, no. 15, p. 2456-2463

A series of arene–ruthenium complexes of the general formula [RuCl2{η6-C6H5 (CH2)2R}L] with R=OH, CH2OH, OC(O)Fc, CH2OC(O)Fc (Fc=ferrocenyl) and L=PPh3, (diphenylphosphino)ferrocene, or bridging 1,1′-bis(diphenylphosphino)ferrocene, have been synthesized. Two synthetic pathways have been used...
