Soluble oxides: The reaction between a β-diketiminate aluminum methyl hydroxide and [M{N(SiMe3)2}2(thf)2] (M=Ca, Sr) results in alkaline-earth-metal oxides such as [{LAl(Me)(μ-O)Ca(thf)}2] (see core structure; L is deprotonated β-diketiminate CH{C(CH2)}(CMe)(2,6-iPr2C6H3N)2). These soluble complexes are dimeric in the solid state and contain unprecedented M2O2 cores.

    ABSTRACT: 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.

    ABSTRACT: The reaction of LAlH(2) (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3)) (1) with 3-methylphenylboronic acid and 3-fluorophenylboronic acid resulted in the boroxine-linked aluminum compounds LAl[OB(3-CH(3)C(6)H(4))](2)(μ-O) (2) and LAl[OB(3-FC(6)H(4))](2)(μ-O) (3), respectively. LAl[OB(2-PhC(6)H(4))(OH)](2) (4) was synthesized by the reaction of 1 with 2-biphenylboronic acid. Compound 4 is the intermediate analogue to those, which we postulated for the formation of 2 and 3. The reaction of 1 with 3-hydroxyphenylboronic acid resulted in the first metal benzoboroxole oxide LAl[OB(o-CH(2)O)C(6)H(4)](2) (5), which is formed from a compound with B-(OH)(2) and C-OH functionalities.

    ABSTRACT: Victor Grignard’s Nobel Prize-winning preparation of organomagnesium halides (Grignard reagents) marked the formal beginning of organometallic chemistry with alkaline earth metals. Further development of this invaluable synthetic route, RX + Mg → RMgX, with the heavier alkaline earth metals (Ca and Sr) was hampered by limitations in synthetic methodologies. Moreover, the lack of suitable ligands for stabilizing the reactive target molecules, particularly with the more electropositive Ca and Sr, was another obstacle. The absence in the literature, until just recently, of fundamental alkaline earth metal complexes with M−H, M−F, and M−OH (where M is the Group 2 metal Mg, Ca, or Sr) bonds amenable for organometallic reactions is remarkable.
