Synthesis and transformations of metallacycles 35. Joint cycloalumination of cyclic 1,2-dienes with disubstituted acetylenes and terminal allenes under the action of EtAlCl2 catalyzed by Ti and Zr complexes

摘要

Catalytic intermolecular cycloalumination of cyclic 1,2-dienes with terminal allenes or disubstituted acetylenes mediated by EtAlCl2 in the presence of complexes based on transition metals was accomplished. The yield of unsaturated bicyclic aluminacarbocycles was up to 85%.
