Chloride Hydrate

Three-component cyclocondensation of β-naphthol, aldehydes, and 5,5-dimethylcyclohexane-1,3-dione (dimedone) was catalyzed efficiently by ruthenium chloride hydrate under mild reaction conditions to afford 12-aryl or alkyl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one derivatives in good to excellent yields.

The one-pot domino Knoevenagel-type condensation/Michael reaction of aromatic, heteroaromatic and aliphatic aldehydes with 4-hydroxycoumarin in aqueous media in the presence of ruthenium salt as homogeneous catalyst was investigated. It was found that 5 mol% of RuCl3.nH2O catalyzes biscoumarin synthesis in high yields (70-95%) under optimised, mild, green and environmentally benign reaction conditions in short times (25-35min).

Double Character

A “double character” FePO4 catalyst, which acts as a homogeneous catalyst at high temperature, was used to produce 5-HMF starting from cellulose and woody biomass without the addition of homogeneous acids.
