1,4- and 1,5-diols undergo cyclodehydration upon treatment with cationic N-heterocyclic carbene (NHC)–IrIII complexes to give tetrahydrofurans and tetrahydropyrans, respectively. The mechanism was investigated, and a metal-hydride-driven pathway was proposed for all substrates, except for very electron-rich ones. This contrasts with the well-established classical pathways that involve nucleophilic substitution.
Non-flammable and reusable hydrogenation of aromatic ketones in ionic liquid

A novel method of hydrogenation of aromatic ketones in the ionic liquid [BHEA][HCO2] was developed; this method is more enhanced in terms of flammability and reusability as compared to the conventional method (H 2 and Pd/C). The redu

γ-Butyltelluro-2-butanol was reacted with 2 equiv of n-butyllithium. Both tellurium/lithium exchange and the proton abstraction reactions took place in a single step and the lithium dianion intermediate efficiently reacted with aldehydes and ketones, producing the corresponding diols.
