“…34 In related work, the use of mixtures of metallic lithium and sodium in the naphthalene-alkali metal systems in THF has been found to lead to a synergistic acceleration of the naphthalene alkylation with ethene at room temperature and atmospheric pressure. 35 Novel dithienostannoles have been synthesised by reactions of the corresponding dilithiobithiophenes with dichlorodiphenylstannane. 36 Lithium 2-vinyl-1,2-azaboratabenzene has been prepared from 2,2-dibutyl-2,5-dihydro-1trimethylsilyl-1H-1,2-azastannole.…”

This chapter provides a non-critical overview of research advances involving the elements of Groups 1 and 2 during the calendar year 2009. As was the case in previous years, coverage will concentrate upon topics centred around the synthesis, structures and applications of coordination compounds of these elements. This self-imposed restriction will necessarily result in the omission of numerous advances in other branches of chemistry and, for this, the author wishes to apologise in advance. HighlightsConcerns over energy supply and storage have resulted in enhanced interest in the application of s-block compounds, either as components of MOF structures or in the synthesis of amidoborane derivatives, as hydrogen storage media. [10][11][12]83,[124][125][126] The study of lower oxidation state alkaline earth [M(I)] species has also gathered momentum with reports of further examples of Mg-Mg bonded species and their reactivity, [129][130][131][132] as well as a unique Ca(I) complex. 141 The application of Group 2 complexes in molecular catalysis has also continued to attract intense international attention. 105,152,[175][176][177][178][179][180][181][182][183]

“…Aromatic hydrocarbon catalytic hydrogenation has a very wide range of industrial applications, while the demand for such compounds in the biological field has led to the further development of methods for aromatic hydrocarbon hydrogenation [8] . There are four main methods for the saturation of aromatics: (1) Reduction of alkali metals such as lithium and sodium; [9] (2) Microbial methods; [10] (3) Electrocatalysis; [11] (4) Catalytic hydrogenation using catalysts and hydrogen sources [12] . Aromatic hydrocarbons have great pollution to the ecological balance.…”

Aromatic hydrocarbons are carcinogenic and can induce mutations in living organisms, posing a threat to the ecological environment and human life and health. Catalytic hydrogenation of aromatics to reduce the saturation of aromatics not only reduces their toxicity, but also greatly increases their potential value. Compared with the unsupported catalysts with only active components, the supported metal catalysts have higher catalytic activity and better selectivity, the catalytic activity of the hydrogenation reaction depends on the metal active phase and catalyst support. On metal/acid catalysts, the metal active center and nearby acid sites are involved in the conversion of aromatics, the active hydrogen leaking from the metal center can hydrogenate the adsorbed aromatics at the acid site. This paper reviews the recent research progress of nickel‐based catalysts for aromatic hydrocarbon catalytic hydrogenation and discusses the development prospects and challenges faced by non‐precious metal catalysts. In addition, the sulfur tolerance and hydrogen storage properties of catalysts for aromatics are reviewed.
