Magnesium ethyl- bromid

Sodium amide 3-Methoxybenzyl cyanide Magnesium Ethyl bromide... 

Magnesium ethyl bromide presumably gives cuprous ethyl, but the compound is unstable above —18° C. and has not been further investigated. 

Thallium diethyl bromide is easily isolated from magnesium ethyl bromide and thallic chloride its solubility falls between that of the chloride and iodide, and it remains unmelted at 300° C. 

The iodide when treated with sodium in xylene solution gives sodium iodide and the unsaturated silicohydrocarbon. With magnesium ethyl bromide, the iodide yields octaphenyldiethylsilico-ietrane which crystallises from aqueous acetone containing a little chloroform in flat, transparent, rhomboidal plates, containing 3 mols, of water of crystallisation. When anhydrous, it melts at 253° to 254° C. when heated with piperidine and sodium hydroxide, it decomposes with evolution of hydrogen. ... 

Tin dimethyl diethyl, Sn CH3)2(C2H5)2, may be obtained in a variety of ways (1) From tin diethyl iodide and zinc methyl. (2) From tii dimethyl iodide and zinc ethyl. (3) By the interaction of magnesium methyl iodide and tin diethyl chloride, bromide, or iodide or by the action of magnesium ethyl bromide on tin dimethyl chloride, bromide, or iodide, the action taking place in ethereal solution. ... 

Tin trifoenzyi ethyl is formed by the interaction of tin tribenzyl chloride and magnesium ethyl bromide, the yield being almost theoretical. The product crystallises from alcohol-petroleum in coloiirless tablets, M.pt, 31° to 32° C., which are easily soluble in ether, benzene, or chloroform, less so in alcohol, and sparingly in light petroleum. 

Ethylphenyl-p-tolylphosphine, (C2Hg)(C6H5)(C7H7)P, may be isolated by treating phenyl-p-tolylchlorophosphine with zinc diethyl or magnesium ethyl bromide. It has an intolerable odour, boils at 340° C., and is readily soluble in concentrated hydrochloric acid. It yields a platinichloride which crystallises m pale yellow needles. 

Triethylphosphine oxide, (C2Hg)gPO, may be obtained by the following methods (1) By the oxidation of triethylphosphine by air, nitric acid or mercuric oxide. (2) By the action of potassium hydroxide on the product resulting from reaction between zinc diethyl and the compound CgHgOPClg. (3) One part of white phosphorus and 13 parts of ethyl iodide are heated together for 24 hours at 175° to 180° C., and the reaction mass then boiled with 97 per cent, alcohol until no more ethyl iodide is formed. The solution is then distilled vith 4 parts of potassium hydroxide. (4) Magnesium ethyl bromide is allowed to react with phosphorus oxychloride and the mixture then decomposed with dilute hydrochloric acid." (5) By heating the reaction product from zinc diethyl and phosphorus oxychloride with potassium hydroxide and a little water. ...
