Alkaline earth metals important reactions involving

Table 18.8 summarizes some important reactions involving the alkaline earth metals. 

The problem of demonstrating the involvement of a metal ion in a biological reaction has always been a very difficult one, since the most important metals (such as the alkali metals, alkaline-earth metals, and zinc) possess very few convenient handles . The replacement of the native metal by a less retiring one has become a well-established technique, and the n.m.r. work of Cohn and her school on systems in which the paramagnetic Mn + ion has been substituted for the diamagnetic Mg + ion needs no introduction. The interaction of transfer-RNA and related compounds with Mn + has recently been demonstrated by the enhancement of the proton relaxation rate (p.r.r.) technique.

MgO and other alkaline earth oxides in pure and doped form play an important role in the eatalytic activation of methane [37]. It is likely that one or several of the metal oxide surface sites involved in the H2 splitting at room temperature are also relevant candidates for methane activation as introductory step for partial oxidation reactions such as oxidative eoupling of metheme (OCM). Particularly encouraging is the fact that H radical production...
