Magnesium tetraorganyl derivatives of group 13 metals as intermediate products in the synthesis of group 13 metal alkyls and aryls
Abstract
<p>Reactions of organomagnesium halides with group 13 metal halides lead to the formation of R<sub>3</sub>M type compounds (R = alkyl, aryl; M = Al, Ga, In) and are considered as the simplest methods of R<sub>3</sub>M compound syntheses. These seemingly simple reactions reveal a much more complex chemistry involving mixed magnesium-group 13 metal compounds. To elucidate the reaction course of reactions of organomagnesium halides with group 13 metal halides, we have studied reactions of R<sub>3</sub>M with organomagnesium halides. The interaction of Et<sub>3</sub>M with R<sup>1</sup>MgX led to the formation of following products being mixtures of crystalline ionic complexes with the general composition of [Et<sub>4-n</sub>R<sup>1</sup><sub>n</sub>M]<sup>−</sup>[XMg (thf)<sub>5</sub>]<sup>+</sup>·(thf): [Et<sub>2.2</sub>Al(CH=CH<sub>2</sub>)<sub>1.8</sub>]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (1), [Et<sub>3</sub>Ga(CH=CH<sub>2</sub>)]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (2), [Et<sub>4</sub>Al]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (3), [Et<sub>4</sub>Ga]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (4), [Et<sub>2.9</sub>Al(C<sub>6</sub>H<sub>5</sub>)<sub>1.1</sub>]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (5), [Et<sub>2.9</sub>Ga(C<sub>6</sub>H<sub>5</sub>)<sub>1.1</sub>]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (6), [Et<sub>3.4</sub>GaMe<sub>0.6</sub>]<sup>−</sup>[IMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (7) and [Et<sub>4</sub>In]<sup>−</sup>[BrMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) (8). A comparison of the production course of group 13 metal trialkyls R<sub>3</sub>M with a thermal decomposition of 1–8 products showed that reactions of MX<sub>3</sub> with RMgX (X = Br, I; R = alkyl, aryl) yield initially intermediate ionic compounds, which must then be thermally decomposed to obtain pure R<sub>3</sub>M compounds. If group 13 metal bromides and iodides, and alkyl (aryl)magnesium bromides and iodides in thf are used, only intermediate products with the [R<sub>4</sub>M]<sup>−</sup>[XMg (thf)<sub>5</sub>]<sup>+</sup>·(thf) structure are formed.</p>
