Designing interactions across interfaces in ionic liquids

Valentin Michael Manzanares

Ionic liquids (ILs) have attracted much attention because of their unusual charac- teristics (vapor pressure, condictivity, etc.). Furthermore, they can be designed to display desired properties specific to an application (task-specific ionic liquid, TSILs ...

Linear Scaling Relationships and Volcano Plots in Homogeneous Catalysis – Revisiting the Suzuki Reaction

Matthew Wodrich, Michael Markus Busch

Linear free energy scaling relationships and volcano plots are common tools used to identify potential heterogeneous catalysts for myriad applications. Despite the striking simplicity and predictive power of volcano plots, they remain unknown in homogeneou ...

Synthesis and reactivity of bis(diphenylphosphino)amine ligands and their application in Suzuki cross-coupling reactions

Rosario Scopelliti

Two new bis(diphenylphosphino) amines, N,N-bis(diphenylphosphino) benzidine 1 and N, N-bis(diphenylphosphino)- 3,3-dimethoxybenzidine 2 were prepared by aminolysis. Their corresponding oxides, sulfides and selenides were readily prepared by reaction with h ...

Palladium Alkynyl and Allenylidene Complexes: Very Efficient Precatalysts for C-C Coupling Reactions

Oxidative addition of BrC CC(=O)O-menthyl (1a) to [Pd(PPh3)(4)] affords the alkynyl complex trans-[Br(PPh3)(2)Pd-C CC(=O)O-menthyl] (2a). Subsequent reaction of 2a with trifluoroacetate gives trans-[(F3CCOO)(PPh3)(2)Pd-C CC(=O)O-menthyl] (3a). Reaction of ...
