Tris gallium

In addition, boron, aluminum, and gallium tris(triduoromethanesulfonates) (tridates), M(OTf)2 and related perduoroalkanesulfonates were found effective for Friedel-Crafts alkylations under mild conditions (200). These Lewis acids behave as pseudo haUdes. Boron tris(tridate) shows the highest catalytic activity among these catalysts. A systematic study of these catalysts in the alkylation of aromatics such as benzene and toluene has been reported (201). 

The triazenide anion, RN=N NR, is formally isolobal with the carboxylate anion. However, while there are no well-characterized examples of gallium tris-carboxylates (see Section 8.7), the (hT-diphenyltriazenide) complex Ga(dpt)3 (14) has been isolated and fully characterized. ...

Gallium tris-/3-diketonate complexes are formed by the addition of acetylacetonate ions to aqueous solutions of Ga + (e.g. equation 22). However, at /3-diketonate to gallium ratios less than three, basic hydroxo complexes are also formed. 

Dimethylcadmium reacts with gallium tris(di-terr-butyl phosphide), Ga(PBu 2)3, to give a trimeric derivative [MeCdPBuSJr crystal structure determination revealed cyclic self-assembly, 27, with trigonally planar coordinated cadmium and a tendency of bond length alternation in the six-membered ring (Cd-P 2.568 and 2.586 A) [49]. This compound serves as a precursor for cadmium phosphide (Cd3P2) nanoparticles [49a].
