Construction of extended π-conjugation systems utilizing novel multicarbene complexes of titanium
Titanium-multicarbene complexes, namely organo-titanium species having a plurality of titanium-carbene complex substructures, were easily prepared by the reaction of aromatic nuclei possessing spatially separated thioacetal moieties with the titanocene(II
Half-sandwich rhodium/iridium(III) complexes designed with Cp* and 1,2-bis(phenylchalcogenomethyl)benzene as catalysts for transfer hydrogenation in glycerol
The reactions of 1,2-bis(phenylthiomethyl)benzene(L1) and 1,2-bis(phenylselenomethyl)benzene(L2) with [(η5-Cp*) MCl(μ-Cl)]2 (M = Rh or Ir) at room temperature, followed by treatment with NH4PF6 have resulted in

Ionic liquid as catalyst and reaction medium: A simple, convenient and green procedure for the synthesis of thioethers, thioesters and dithianes using an inexpensive ionic liquid, [pmIm]Br
An easily accessible and inexpensive room temperature ionic liquid, 1-pentyl-3-methylimidazolium bromide, [pmIm]Br efficiently catalyzes the reaction of alkyl halides or acyl halides with thiols without any solvent at room temperature leading to the synthesis of thioethers and thioesters in high yields. This reaction has also been extended for the preparation of dithianes and transthioetherification. The ionic liquid is recovered and recycled for subsequent runs.
