“…Spencer and Wallace (417) observed reactions between aluminum and a variety of organic halides with the probable formation of organoaluminum compounds, but in all cases the reaction products were treated with water, and consequently no organoaluminum derivatives were isolated. Other investigations (183,215) have shown that the reaction of aluminum with organic halides is a method of choice for making organoaluminum compounds. Aluminum-copper alloy (8 per cent copper) and methyl chloride (215), with 0.1 per cent aluminum chloride as catalyst, reacted to give an equimolar mixture of dimethylaluminum chloride and methylaluminum dichloride in an almost quantitative yield.…”

“…The two iodides isolated by them, namely (C2H5)2A1I and C2H6A1I2 were the only known organoaluminum halides when our work was begun. Subsequently Hall and Nash (7) described the isolation of diethylaluminum chloride; and Hnizda and Kraus (8) reported the separation of the two methylaluminum chlorides prepared from the reaction of methyl chloride with aluminum. The latter reaction was also investigated by Walker and Wilson (9).…”

“…Disproportionation went still further, in fact, during the removal of the first dimethylaluminum iodide fractions, giving a distillate containing 2 to 3% of aluminum trimethyl 8. Aluminum triphenyl was prepared in the conventional manner from mercury diphenyl and aluminum.…”

36 These figures include in addition to the organoaluminum compounds, any combinations which can be made from inorganic substituents. 4 In the text, "Die Chemie der metall-organischen Verbindungen" by E. Krause and one of the authors, the term "alphyl" is used to denote the aliphatic radicals, and "alkyl" in a broader sense to include both aliphatic and aromatic groups. Conforming to common usage in this country, the term alkyl as used in the present paper refers only to aliphatic radicals. 106 SUMMARY 1. Organoaluminum compounds have been prepared by the reaction of aluminum metal with a series of alkyl halides. These halides are methyl and ethyl chlorides, bromides and iodides, and n-propyl iodide.2. By diverse methods each of the dialkylaluminum halides and alkylaluminum dihalides corresponding to the above alkyl halides has been obtained in pure form.3. The preparation of phenylaluminum dichloride, dibromide, diiodide and p-tolylaluminum diiodide is described.4. Alkylaluminum alkoxides have been prepared by the reaction of aluminum alkyls with aluminum alkoxides.5. Dialkylaluminum halides have been prepared directly by the reaction of alkyl halides with an aluminum-magnesium alloy.6. A new method for preparing aluminum alkyls involving the reaction of alkylaluminum halides with alkali metals is described. Riverside, III.

Slight modifications, apported in the synthesis of (CH3)2AsX (X = Cl, Br) (I, II) by the reduction of cacodylic acid by underfosforic acid, are reported. (CH3)2AsI (III) was prepared in a high purity state. An improved method is given for the preparation of CH3AsCl2 (IV) and the yield is raised from 55 to 70%. CH3AsBr2 (V) up to now unknown, was prepared by a method analogous to that for (IV). In (CH3)2 (VI) was prepared by the action of Hg(CH3)2 on In; with high‐purity Hg(CH3)2 it is necessary to add traces of I2 and Mg together with HgCl2, as catalysts; reaction starts within two hours. We succeeded the synthesis of [(CH3)2AlX]2 (X = Cl, Br, I) (VII, VIII, IX) and of [CH3AlX2]2 (X = Cl, Br) (X, XI) in an all‐glass apparatus under atmospheric pressure; decantation of the sesquihalogenides from the slurry of unreacted Al was avoided.
