Hydro-, Carbo-, and Cycloalumination of Unsaturated Compounds

This chapter gives a survey and a systematic account of modern achievements in the synthesis of acyclic and cyclic organoaluminum compounds using thermal and catalytic hydro- and carboalumination of unsaturated compounds. Here we consider a new, versatile catalytic cycloalumination reaction of olefins, acetylenes, and 1,2-dienes of various structures with alkyl and halogen alkyl Al catalyzed by Zr and Ti complexes to give previously unknown classes of OACs: aluminacyclopropanes, aluminacyclopropenes, aluminacyclopentanes, aluminacyclopentenes, aluminacyclopentadienes, and aluminamacrocarbocycles. Much attention is given to applications of hydro-, carbo-, and cycloalumination reactions for the synthesis of practically important natural carbo- and heterocyclic compounds.
