Organometallic chemistry is based on the reactions and use of a class of compounds (R-M) that contain a covalent bond between carbon and metal. They are prepared either by direct reaction of the metal with an organic compound or by replacement of a metal from another organometallic substance. Research in organometallic chemistry is also conducted in the areas of cluster synthesis, main-group derivatives in unusual oxidation states, organometallic polymers, unstable organometallic compounds and intermediates in matrices, structure determination of organometallic compounds in the solid state [X-ray diffraction] and gaseous states [electron diffraction], and mechanisms of reactions of transient silylenes and related species. In addition to the traditional metals and semimetals, elements such as selenium, lithium and magnesium are considered to form organometallic compounds, e.g. organomagnesium compounds MeMgI, iodo(methyl)magnesium and diethylmagnesium which are Grignard reagents an organo-lithium compound BuLi butyllithium. Organometallic compounds often find practical use as catalysts, the processing of petroleum products and the production of organic polymers.
The modern welfare state is indeed one of the greatest achievements of the post-war 20th century. With its key aims of eradicating the five giant social ills of Want, Ignorance, Disease, Squalor and Idleness, it aimed to providing a minimum standard of living, with all people of working age paying a weekly contribution; in return, benefits would be paid to anyone who was sick, unemployed, retired or widowed. The modern welfare state, therefore, is about maintaining a delicate equilibrium between dependent social groups on the one hand and the active working classes on the other. In the case of old-age security, this balance is being achieved (or not) by the so-called Generation Contract. This social pact is more of an implicit, unwritten and unspecified social contract. This ground-breaking book demonstrates how countries are addressing population-ageing challenges in depth, using the case study of Austria to gain the required complexity and differentiation in a comparative European framework of empirical evidence. This is a broad social science study in political economy and sociology, not an economic analysis. Though focusing on pensions, it centres on the (im)balance between work and non-work, issues of health, work ability, employability, and benefit receipt from old-age security to disability allowance. It will be required reading for all sociologists and social policy experts and academics working within this area.
