N,N-Dimethylformamide-stabilized ruthenium nanoparticle catalyst for β-alkylated dimer alcohol formation via Guerbet reaction of primary alcohols

Abstract

N,N-Dimethylformamide-stabilized Ru nanoparticles (NPs) provide a highly efficient catalyst for the Guerbet reaction of primary alcohols under solvent-free conditions and without the use of external ligands.

Dimethylacetamide-stabilized ruthenium nanoparticles for catalysing α-alkylations of amides with alcohols

“…The catalytic activities of the synthesized NPs in alkylations of amides were higher than those previously reported for NPs prepared by using DMF. 13 The synthesized solutions emitted light when irradiated by black light and showed fluorescent properties.…”

“…When Ru NPs (DMF) were used, the yield of the desired product was lower than when Ru NPs (DMAc) were used (entry 4). 13 The catalytic activity of Ru NPs (DMF) is relatively low due to the strong carbonyl coordination on the Ru metal center at approximately 1950 cm À1 in the FT-IR spectrum (Fig. S6, ESI †).…”

“…S6, ESI †). 13 This reaction proceeded in the presence of both a base and a catalyst (entries 5 and 6). Two equivalents of base were required, and the yield decreased significantly when the amount was halved (entry 7).…”
