Abstract: 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… read more here.

Abstract: The large steric profile of the N-heterocyclic boryloxy ligand, –OB(NDippCH)2, and its ability to stabilize the metal-centered HOMO, are exploited in the synthesis of the first example of a “naked” acyclic aluminyl complex, [K(2.2.2-crypt)][Al{OB(NDippCH)2}2]. This… read more here.

Abstract: (NONDipp)Al-K(TMEDA)2 (NONDipp = [O(SiMe2NDipp)2]2-, Dipp = 2,6-iPr2C6H3), containing an Al-K bond, activates and reductively couples cabon monoxide gas to form the [C4O4]4- ligand. This oxocarbon anion is thermally isomerised in the presence of CO and… read more here.

Abstract: The previously reported potassium aluminyl complex [(BDI-H)Al-K+]2 was converted in Li+ or Na+ salts by a salt metathesis reaction with Li(BPh4) or Na(BPh4), respectively; BDI-H = dianionic [(DIPP)N-C(Me)C(H)-C(CH2)-N(DIPP)2-] and DIPP = 2,6-diisopropylphenyl. The Rb and… read more here.
