The reactivity of the aluminacyclopropane compound K[Al(NON)(η2-C2H4)] (NON = κN,N’-[O(SiMe2NDipp)2]2–; Dipp = 2,6-iPr2C6H3) toward isocyanides R–NC (R = Cy, Ad, tBu; Cy = cyclohexyl, Ad = 1-adamantyl...

The reaction of the potassium aluminyl K[Al(NON)] ([NON]2– = [O(SiMe2NDipp)2]2–, Dipp = 2,6-iPr2C6H3) with the stannylene Sn[N(SiMe3)2]2 in benzene afforded K3[(Sn4){Al(NON)}2{N(SiMe3)2}], containing...

The synthesis of a new potassium gallyl system, K[Ga(NON)] ([NON]2– = [O(SiMe2NDipp)2]2–, Dipp = 2,6-iPr2C6H3), has been reported, and its reactivity toward a variety of ketones has been studied. The potassium gallyl is initially isolated as the contacted dimeric pair (CDP) [K{Ga(NON)}]2 but can be converted to the monomeric ion pair (MIP) (NON)Ga–K(TMEDA)2 or the separated ion pair (SIP) [K(222-crypt)][Ga(NON)] upon addition of coordinating polydentate ligands. The reaction of the CDP with two equivalents of benzophenone or 9-fluorenone per gallium center generates homocoupled pinacolate products. However, the reaction with acetophenone initially forms a gallium 1,3-phenylethene-1-olate, which C–C couples to a second equivalent of acetophenone to form an unprecedented gallium 1,3-diphenylbutane-1,3-diolate. This reactivity is contrasted with the analogous potassium aluminyl CDP [K{Al(NON)}]2, where preferential formation of the pinacolate product is observed under the same reaction conditions.

The potassium aluminyl K[Al(NON)] ([NON]2– = [O(SiMe2NDipp)2]2–, Dipp = 2,6-iPr2C6H3) reacts with group 14 chloroamidinates E{14}(Am)Cl (E{14} = Ge, Sn, Pb. [Am]– = [tBuC(NDipp)2]–) to form (NON)Al–E....
