Cyclization of Citronellal to Isopulegol Catalyzed by Temperature‐Stable Aluminum Complexes with Tripodal Tris(silanolate) Ligands

ChemistryEurope, Volume 4, Issue 1, January 2026.
C3‐Symmetric aluminum chelate complexes endowed with tripodal tris‐silanolate ligands are shown to be excellent catalysts for the selective carbonyl ene‐type cyclization of citronellal to isopulegol as the key intermediate of the current industrial syntheses of menthol.

Well‐Defined Rhodium and Iridium Complexes Containing Chiral Cyclic(Alkyl)(Amino)Carbenes for Asymmetric Hydrogenation

ChemistryEurope, Volume 4, Issue 1, January 2026.
A set of fourteen well‐defined rhodium and iridium complexes containing various enantiopure cyclic(alkyl)(amino)carbene (ChiCAAC) ligands (>96% ee to > 99.5% ee) has been synthesized and fully characterized. While no enantioselectivity is observed with chiral Rh‐CAAC, the Ir‐CAAC counterparts demonstrated good performances in the asymmetric ...

Copper‐Catalyzed Defluorinative Allylboration of Allenes with Trifluoromethyl Alkenes

ChemistryEurope, Volume 4, Issue 1, January 2026.
A copper‐catalyzed borylative coupling of allenes with 1‐trifluoromethyl alkenes is reported. The reaction selectively provides synthetically versatile borylated 1,1‐difluoro‐1,5‐dienes that can be converted into a range of medicinally relevant fluorinated compounds. Mechanistic studies reveal a key role of the catalytically generated LiCl by assisting
