Herein the synthesis of a new ethynyl ferrocenyl amidinate ligand [Fc?C?C-{C(Ndipp)$_{2}$H}] (Fc=ferrocenyl; dipp=diisopropylphenyl) and subsequent formation corresponding samarium amido complex [Sm{Fc?C?C-[C(Ndipp)$_{2}$$_{2}$]}$_{2}${N(SiMe$_{3}$3)$_{2}$}] is reported. [Fc?C?C-{C(Ndipp)2H}] [Sm{Fc?C?C-[C(Ndipp)$_{2}$]}$_{2}${N(SiMe$_{3}$)$_{2}$}] were fully characterized including study compl...

The role of the redox-active tripeptide glutathione in plant defence against pathogens has been studied extensively; however, the impact of changes in cellular glutathione redox potential on signalling processes during defence reactions has remained elusive. This study explored the impact of elevated glutathione content on the cytosolic redox potential and on early defence signalling at the lev...

The supported K2O–V2O5/Al2O3 catalytic system was designed to create surfaces that were 100% acidic, 100% basic, 100% redox, mixed redox-acidic and mixed redox-basic. The resulting nature of the surface sites was controlled by the impregnation of the specific additives (K-basic or V-redox/acidic), their order of impregnation and their surface coverage. The exact locations of the surface methoxy...

Elicitor preparations containing the avr5 gene products from races 4 and 2.3 of Cladosporium fulvum, and tomato (Lycopersicon esculentum L.) cells containing the resistance gene Cf5 were used to investigate the involvement of redox processes in the production of active oxygen species associated with the plant response to the fungal elicitors. Here we demonstrate that certain race-specific elici...

The ring size effect of macrocyclic TMC ligands in nonheme iron(IV)-oxo complexes has been examined in hydrogen atom transfer (HAT) and oxygen atom transfer (OAT) reactions; an iron(IV)-oxo complex bearing a smaller TMC ligand is more reactive in both HAT and OAT reactions, resulting from its high Fe(IV/III) redox potential.
