The homoleptic alkaline earth hexamethyldisilazides, [M{N(SiMe3)2}2(THF)2] (M = Mg 1a; Ca 1b; Sr 1c), have been shown to act as efficient precatalysts for the hydroacetylenation of organic carbodiimides with alkyl- and arylacetylenes. Catalytic activity was observed to increase with...

We report the synthesis and characterization of the first eta(3)-1,3,5-trimethyl-1,3,5-triazacyclohexane (Me(3)TAC) alkoxo complexes. Dehydration of [Co(H(2)O)(6)](X)(2) with 2,2-dimethoxypropane or HC(OMe)(3) and subsequent treatment with Me(3)TAC results in the formation of the methoxo cube fragment clusters [{(Me(3)TAC)Co}(3)(OMe)(4)](X)(2) (X = B(C(6)F(5))(4)...
