The activation of small alkane molecules originating from natural gas or renewable resources on metal oxide surfaces regains increasing scientific interest since direct utilization of saturated hydrocarbons will offer alternative pathways to higher value chemicals in a postpetroleum era. The focus of the project lies on oxidation catalysis of small alkane molecules including methane, ethane, pr...

The synthesis of the thermally stable bicyclic diphosphasilirane O(SiiPr2P)2SiiPr2 (4) was achieved via oxidation of the alkaline earth metal substituted cyclic diphosphanide 3 with 1,2-dibromoethane. Nonetheless, during extended storage at low temperature, impurity induced rearrangement in favour of the dimeric species [O(SiiPr2P)2SiiPr2]2 (5) is observed.

Introduction Elemental beryllium is a steel gray appearing alkaline earth metal with properties like brittleness and high rigidity being the lightest among metals. The majority of beryllium is found in minerals and soils rather than in its elemental form. Beryllium is found in about 30 different mineral species like different compounds including aluminium e.g. Beryl (beryllium aluminium silicate).

A new [2+2] tetra-hydrazone macrocyclic receptor was significantly amplified in a dynamic combinatorial library upon templation with alkaline earth metal ions. After optimisation the product could be isolated in 95% yield and its interaction with ions was investigated by NMR and UV-Vis spectroscopy.

group viii b metal oxides supported on gamma-alumina were investigated as catalysts and promoters of moo3 hydrodesulfurization catalysis. superior promotion was observed in pbo promoted catalyst compared to that of coo, the typically accepted promoter. other metal oxides, sno and ho2o3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for coo promoted catalyst.
