The available experimental data for metallic solid solutions in the rhenium-rhodium binary metallic system are incomplete. This paper reviews recent data on the Re-Rh system which enables the solidus parts of the equilibrium phase diagram to be constructed. Experimental data for solid solutions prepared by different techniques and theoretical modelling show that the single phase regions are wider than previously reported. The maximum solid phase solubility of Re in Rh is 15 at%, and that of Rh in Re is 75 at%. In this paper, a phase diagram for the Re-Rh system which serves as a reliable model for the representation of the available experimental data is proposed.

Johnson Matthey, Catalysis and Chiral Technologies, 2001 Nolte Drive, West Deptford, New Jersey 08066, USA; E-mail: colactj@jmusa.com The 2010 Nobel Prize in Chemistry was awarded jointly to Professor Richard F. Heck (University of Delaware, USA), Professor Ei-ichi Negishi (Purdue University, USA) and Professor Akira Suzuki (Hokkaido University, Japan) for their work on palladium-catalysed crosscoupling in organic synthesis. This article presents a brief history of the development of the protocols for palladium-catalysed coupling in the context of Heck, Negishi and Suzuki coupling. Further developments in the area of palladium-catalysed cross-coupling are also briefly discussed, and the importance of these reactions for real world applications is highlighted.
