A convenient alumination of functionalized aromatics by using the frustrated Lewis pair Et₃Al and TMPMgCl-LiCl was written by Unsinn, Andreas;Wunderlich, Stefan H.;Jana, Anukul;Karaghiosoff, Konstantin;Knochel, Paul. And the article was included in Chemistry – A European Journal in 2013.Recommanded Product: 371764-70-4 The following contents are mentioned in the article:

A straightforward and efficient alumination of functionalized arenes, in particular, halogenated electron-rich aromatic compounds, with Et₃Al and stoichiometric amounts of frustrated Lewis pair TMPMgCl-LiCl (TMP = 2,2,6,6-tetramethylpiperidyl) as a co-reactant, has been developed. In particular, halogenated electron-rich aromatics can be smoothly functionalized by using the frustrated Lewis pair Et₃Al and TMPMgCl-LiCl. Compared with previously described alumination methods, this procedure avoids extensive cooling and the need for an excess of base. This in situ procedure has proven to be most practical and allows for regio- and chemoselective metalation of a wide range of aromatics with sensitive functional groups (CONEt₂, CO₂Me, CN, OCONMe₂) or halogens (F, Cl, Br, I). The resulting aromatic aluminates, which were characterized by using NMR spectroscopy, were subjected to allylations, acylations, and palladium-catalyzed cross-coupling reactions after transmetalation to zinc. It was shown that the nature of the Zn salt used for transmetalation is crucial. Thus, compared with ZnCl₂ (2 equiv), the use of Zn(OPiv)₂ (2 equiv; OPiv=pivalate) allows the subsequent quenching reactions to be performed with only a slight excess of electrophile (1.2 equiv) and provides interesting functionalized aromatics in good yields.
