Synthesis, Characterization, and Applications of Group 13 Cationic Compounds

New Perspectives for Aminotroponiminates: Coordination Chemistry, Redox Behavior, Cooperativity, and Catalysis

“…Compounds 27‐R catalyze the head‐to‐tail dimerization of tert ‐butylacetylene ( 28 ) to give 29 in > 90 % selectivity with a turnover frequency of ca. 4 h –1 at 23 °C (Scheme a) , , . With ethylene, 27‐Et undergoes chain transfer reactions as demonstrated in deuteration experiments (Scheme b), but no pronounced polymerization activity was observed.…”

“…They are distinguished from these types of ligands by a rigid C 7 ligand backbone, which is a prominent structural feature of the ATI ligand family. ATIs have found application in the stabilization of cationic group 13 complexes, as substitutes for cyclopentadienide ligands in lanthanoid chemistry,, for the synthesis of hyper‐ and hypo‐valent group 14 compounds,, in the investigation of spin delocalization of first row‐transition metal complexes, and in hydroamination catalysis . These fields have been covered elsewhere by the cited review articles.…”

From rational design of organometallic precursors to optimized synthesis of core/shell Ge/GeO2nanoparticles

“…13,28,29 Precursor synthesis and characterization Bis(amidinato)germylene 3 was prepared by treatment of Cl 2 Ge·dioxane with the lithium amidinate salt in a 1 : 2 stoichiometry according to the method previously described (Scheme 3). 30 This germanium(II) species was isolated as a pale yellow powder which is stable under an inert atmosphere and can be stored for long periods at low temperature (−30°C).…”

Synthesis, structure, and reactivity of AlMe2(1-Me-CB11F11): An AlMe2+ cation-like species bonded to a superweak anion

“…Cationic aluminum complexes are of considerable interest due to their potential use in a variety of organic and catalytic transformations [1][2][3][4][5][6][7]. The most reactive are undoubtedly the cation-like species AlR 2 + bonded to carborane and borane superweak anions, which have been isolated and characterized by Reed and co-workers (AlEt 2 (CB 11 H 6 Cl 6 ) and AlEt 2 (CB 11 H 6 Br 6 )) [7] and by Knapp and co-workers ((AlMe 2 ) 2 (B 12 Cl 12 ) and (AlEt 2 ) 2 (B 12 Cl 12 )) [2].…”
