environmentally benign bis-SO3H-functionalized Brønsted acidic ionic liquids were synthesized by using aliphatic polyamines and 1,3-propanesultone as the source chemicals. These ionic liquids acted as efficient inexpensive and recyclable catalysts for cyclotrimerization of aliphatic aldehydes at room temperature under solvent-free conditions. The reactions proceeded smoothly with good to excellent isolated yields
Efficient Oxidative Cleavage of Olefins to Carboxylic Acids with Hydrogen Peroxide Catalyzed by Methyltrioctylammonium Tetrakis(oxodiperoxotungsto)phosphate(3−) under Two-Phase Conditions. Synthetic Aspects and Investigation of the Reaction Course
The oxidativecleavage of alkenes to carboxylicacids with 40% w/v aqueous hydrogen peroxide catalyzed by methyltrioctylammonium tetrakis(oxodiperoxotungsto)phosphate(3-) (Ia) is reported to occur in high yields and selectivities under two-phase conditions in the absence of organic solvents. On the basis of a study of the reaction, two main reaction pathways leading to acids have been recognized, the

The tris(2-pyridyl)phosphine complex [P(2-py)(3)W(CO)(NO)(2)](BF4)(2) acts as a Lewis acid catalyst precursor for the tandem reactions of Friedel-Crafts/aldehyde cyclotrimerization, which lead to the formation of a series of hyper-branched star polymers.
