Diarylphenoxy aluminum compounds |
| abstract |
The present invention relates to diarylphenoxyaluminum compounds obtainable by reacting a bis (diarylphenol) ligand of the formula (I) with an alkylaluminum compound and / or a complex aluminum hydride.n n n The invention further relates to the use of such diarylphenoxyaluminum compounds as catalysts.n n n Moreover, the invention relates to a process for the preparation of isopulegol by cyclization of citronellal in the presence of diarylphenoxyaluminum compounds as catalysts.n n n The invention also relates to a process for the preparation of menthol by cyclization of citronellal in the presence of diarylphenoxyaluminum compounds as catalysts and subsequent hydrogenation. |
