Reactivity of Boryl- and Silyl-Substituted Carbenoids toward Alkynes: Insertion and Cycloaddition Chemistry

Autor: Simon Aldridge, Andrew D. Schwarz, Philip Mountford, Andrey V. Protchenko, Matthew P. Blake, Cameron Jones

Publikováno v: Organometallics. 34:2126-2129

Three modes of reactivity of phenyl-substituted alkynes toward acyclic tetrelenes are reported, with reaction pathways found to be dependent not only on the nature of the group 14 element but also on the supporting ligand set. Systems featuring Sn–

Reduction of indium boryl precursors to give two- and three-dimensional M−M bonded networks is influenced by the choice of supporting ligand. While the unprecedented nanoscale cluster [In(boryl)] (with an In@In@In(boryl) concentric structure), can

Oxidative Bond Formation and Reductive Bond Cleavage at Main Group Metal Centers: Reactivity of Five-Valence-Electron MX2 Radicals

Autor: Simon Aldridge, Andrew D. Schwarz, Philip Mountford, Andrey V. Protchenko, Deepak Dange, Cameron Jones, Matthew P. Blake

Publikováno v: Journal of the American Chemical Society. 136:10902-10905

Monomeric five-valence-electron bis(boryl) complexes of gallium, indium, and thallium undergo oxidative M–C bond formation with 2,3-dimethylbutadiene, in a manner consistent with both the redox properties expected for MII species and with metal-cen

The chemistry of the Group 13 metals is dominated by the +1 and +3 oxidation states, and simple monomeric M(II) species are typically short-lived, highly reactive species. Here we report the first thermally robust monomeric MX2 radicals of gallium, i

Syntheses and Structural Diversity of Group 2 and Group 12 Tris(pyrazolyl)methane and Zwitterionic Tris(pyrazolyl)methanide Compounds

Autor: Andrew D. Schwarz, Michael G. Cushion, Ignacio Fernández, Jens Meyer, Alex Heath, Philip Mountford, Frank Breher

Reaction of HC(Me2pz)3 with Mg(N(SiMe 3)2}2 gave the zwitterionic amide complex Mg{C(Me2pz)3}{N(SiMe3)2} (13), containing a "free" pyramidal carbanion and a cationic {Mg-N(SiMe 3)2}+ moiety. Reaction of the less bulky amide Mg{N(SiHMe2)2}2 with RC(Me
