The low-temperature structure of diethyl ether magnesium oxybromide
The crystal structure of the title compound, hexa-μ(2)-bromido-μ(4)-oxido-tetra-kis-[(diethyl ether)magnesium], [Mg(4)Br(6)O(C(4)H(10)O)(4)], determined from data measured at 173 K, differs from the previously known structure of diethyl ether magnesium oxybromide, which was determined from room-temperature data [Stucky & Rundle (1964 ▶). J. Am. Chem. Soc. 86, 4821-4825]. The title compound crys...
متن کاملPolyribosome Isolation in the Presence of Diethyl Pyrocarbonatel
Isolation of polyribosomes from wheat embryos and corn root tips in the presence of diethyl pyrocarbonate showed this reagent to have a protective effect on polyribosome structure. In addition, the use of diethyl pyrocarbonate allowed initial homogenization to be performed under less stringent conditions than those normally employed for polyribosome isolation. The use of the reagent is however ...

متن کاملDi-l-bromido-bis[benzyl(diethyl ether)- magnesium]
The title benzyl Grignard reagent, [Mg2Br2(C7H7)2(C4H10O)2], was obtained by reaction of benzyl bromide with magnesium in diethyl ether, followed by crystallization from toluene. The asymmetric unit comprises one half-molecule, the structural dimeric unit being generated by inversion symmetry with an Mg Mg distance of 3.469 (2) Å. The Mg(II) atom exhibits a distorted tetrahedral coordination ge...

The title benzyl Grignard reagent, [Mg(2)Br(2)(C(7)H(7))(2)(C(4)H(10)O)(2)], was obtained by reaction of benzyl bromide with magnesium in diethyl ether, followed by crystallization from toluene. The asymmetric unit comprises one half-mol-ecule, the structural dimeric unit being generated by inversion symmetry with an Mg⋯Mg distance of 3.469 (2) Å. The Mg(II) atom exhibits a distorted tetrahedra...
