  2. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  3. Ethylmagnesium bromide - Wikipedia

    en.wikipedia.org/wiki/Ethylmagnesium_bromide

    Ethylmagnesium bromide is commercially available, usually as a solution in diethyl ether or tetrahydrofuran. It may be prepared in the normal manner of Grignard reagents — by reacting bromoethane with magnesium in diethyl ether : [ 2 ]

    en.wikipedia.org/wiki/Michael_Addition_Reaction

    For example, the image below shows the addition of ethylmagnesium bromide to ethyl sorbate 1 using a copper catalyst with a reversed josiphos (R,S)-(–)-3 ligand. [35] This reaction produced the 1,6-addition product 2 in 0% yield, the 1,6-addition product 3 in approximately 99% yield, and the 1,4-addition product 4 in less than 2% yield.

    en.wikipedia.org/wiki/Grignard_reagent

    Mechanical methods include crushing of the Mg pieces in situ, rapid stirring, and sonication. [4] Iodine, methyl iodide, and 1,2-dibromoethane are common activating agents. The use of 1,2-dibromoethane is advantageous as its action can be monitored by the observation of bubbles of ethylene. Furthermore, the side-products are innocuous:

    2 CH 3 MgX + 2 dioxane ⇌ (CH 3) 2 Mg + MgX 2 (μ-dioxane) 2 ↓. In such procedures, the dimethylmagnesium exists as the ether adduct, not the polymer. [4] Addition of 1,4-dioxane causes precipitation of solid MgX 2 (μ-dioxane) 2, a coordination polymer. [4] This precipitation drives the Schlenk equilibrium toward (CH 3) 2 Mg. Related ...
