The allylic substitution reaction, and particularly the direct allylic amination reaction, of free allylic alcohols in water catalyzed by FeCl3⋅6 H2O is described. This novel environmentally-friendly methodology allows the use of a wide variety of nitrogenated nucleophiles such as sulfonamides, carbamates, benzamides, anilines, benzotriazoles, and azides, generally giving good yields of the corresponding substitution products. The synthetic applicability of the process is also demonstrated because the reaction can be performed on gram-scale. Additionally, carbon nucleophiles such as silylated nucleophiles, aromatic compounds, and malonates also proved to be suitable for this transformation. Finally, the nature of the catalytic species present in aqueous media is unveiled, pointing towards the formation of hexaaquo iron(III) complexes.

This paper proves that the real projection of each simple zero of any partial sum of the Riemann zeta function ζn(s):=∑nk=11ks,n>2 , is an accumulation point of the set {Res : ζ n (s) = 0}.

In this paper we provide the proof of a practical point-wise characterization of the set RP defined by the closure set of the real projections of the zeros of an exponential polynomial P(z) = Σn j=1 cjewjz with real frequencies wj linearly independent over the rationals. As a consequence, we give a complete description of the set RP and prove its invariance with respect to the moduli of the c′ js, which allows us to determine exactly the gaps of RP and the extremes of the critical interval of P(z) by solving inequations with positive real numbers. Finally, we analyse the converse of this result of invariance.

In an age of major power shifts, which we know from history always to be particularly dangerous, different scenarios are possible; the only promising one is that of more and well-structured international cooperation. Yet, critical voices point at a drifting apart of longstanding allies. Recalibrating CSDPNATO relations has become more important than ever.

This paper sketches the main features and issues related to recent market developments in global transaction banking (GTB), particularly in trade finance, cash management and correspondent banking. It describes the basic functioning of the GTB, its interaction with global financial markets and related implications of global regulatory developments such as Basel III. The interest in GTB has recently increased, since its low-risk profile, tendency to follow growth rates worldwide and relative independence from other financial instruments became an interesting diversification opportunity both for banks’ business models and for investors. Transaction banking has been a resilient business during the crisis, despite the reduction in world trade figures. In the post crisis period, GTB must cope with new challenges related to increased local and global regulation and the risk of inconsistency in regulatory approaches, which could negatively impact the global network and increased competition by new market entrants. Increased sophistication of corporate clients, as well as the pressure to develop and adopt technological innovations more quickly than other areas of banking continues to impact the business. The future of the industry closely depends on its ability to adjust to complex regulatory developments while at the same time being able to operate a global and efficient network.

In the post-war era, Germany has undergone a deep change almost like clockwork every two decades. In 1949, the foundations were laid for the establishment of the two German states: the Federal Republic of Germany and the German Democratic Republic; 1968–1969 was the time of the student revolt as a harbinger of the democratisation and liberalisation of society; and in 1989–1990, the process of unification took place, with all its consequences. Two decades later, another deep revision of the values is happening, as a consequence of which Germany is bidding a final farewell to the post-war epoch and its inherent certainties: its advancing society, the homogeneous national state and the faith in Europe as a solution to the ‘German question.’ This revision will not be revolutionary. However, as with the previous turning points, Germany is becoming a different state and a different society, which Europe will have to build its relations with anew.

The functions of the financial system of a developed economy are often badly understood. This can largely be attributed to free-market ideology, which has spread the belief that leaving finance to its own devices would provide the best possible mechanism for allocating savings. The latest financial crisis has sparked the beginnings of a new awareness on this point, but it is far from having led to an improved understanding of the role of the financial institutions. For many people, finance remains more an enemy to be resisted than an instrument to be intelligently exploited. Its institutions, which issue and circulate money, play an important role in the working of the real economy that it would be imprudent to neglect. The allocation of savings, but also the level of activity and the growth rate depend on it. In this book, the authors carefully analyse the close links between money, finance and the real economy. In the process, they show why today the existence of a substantial potential of saving, instead of being an opportunity for the world economy, could threaten it with ‘secular stagnation’.
