Dimagnesium(I) complexes [{(Arnacnac)Mg}2], where Arnacnac = HC(MeCNAr)2, Ar Dip 2,6-iPr2-C6H3, Dep 2,6-Et2-C6H3, Mes 2,4,6-Me3-C6H2, react with iodoarenes in oxidative addition reactions. With iodobenzene, magnesium phenyl and iodide complex fragments were obtained, from a reaction 4-iodo-1,2,3,5-tetramethylpyrazolium iodide, [MePZI]I, the pyrazol-4-ylidene [(Dipnacnac)MgI(MePZ)] was structura...
The reactivity of bis-TMS-substituted C,C-diacetylenic phosphaalkene (A(2)PA) 1 in Sonogashira-Hagihara cross-coupling reactions has been examined. The selective and successive deprotection of the two silyl groups in 1 is enabled by the steric bulk of the Mes* group which renders the acetylene trans to Mes* more reactive and thereby facilitates selective and consecutive couplings with iodoarene...
