Recent Advances in Aluminum Compounds for Catalysis

Abstract: This review highlights recent advances in the research of organoaluminum complexes in catalysis. Many fundamental transformations can be carried out by aluminum catalysts, such as hydroboration, hydroamination, copolymerization and CO 2 insertion reactions, hydrosilylation, and hydroacetylenation of carbodiimides, which make use of the abundant reserves of aluminum in the earth's crust to accomplish the transformation. Recent research in the field has shown that these systems have extraordinary catalytic activ… Show more

“…Although complete conversion of HBpin does not occur even at extended reaction times (5 days) 3 has a TOF of 0.08 h −1 (see Supporting Information). It therefore falls within the range of other reported main group systems for CO 2 hydroboration (0.07‐14.5 h −1 ), [37–42] but is a rare example of a single component system [43] operating at room temperature with HBpin as the reducing agent [23,39,42] . To our knowledge, the only other example based on aluminium is the square planar calix[4]pyrrolato aluminate reported by Greb (TOF=0.12 h −1 ) [23] .…”

“…A further impetus comes from higher sigma donation of 5-SIDipp than 5-IDipp, which will make 1 a better sigma donor than its unsaturated congener. We chose aluminum because molecular aluminum hydrides have recently emerged as excellent catalysts on the landscape of molecular catalysis and fuel storage materials . The installation of the nitrogen atom was achieved by the treatment of 5-SIDipp with bromine, followed by the addition of aqueous ammonia.…”

“…Therefore, a growing interest in research concerning alternative catalysts, which should be active, selective and stable as well as solve problems resulting from the use of conventional acids, is of high importance [ 6 , 7 , 8 ]. On the other hand, salts of various metals, such as boron, aluminium, gallium, indium or noble metals, e.g., copper, are also successfully used in catalysis [ 9 , 10 , 11 , 12 , 13 , 14 ], especially in the form of halometallates, because they represent high Lewis acidity, which distinguishes them from other groups of salts. The subjects of this review are metal-based ionic liquid focusing on gallium(III) and indium(III) and their performance in organic chemistry.…”
