Ytterbium Triflate: A Green Catalyst

Abstract

This feature focuses on a reagent chosen by a postgraduate, highlighting the uses and preparation of the reagent in current research Ytterbium Triflate: A Green Catalyst Compiled by Carina I. C. Crucho Carina I. C. Crucho was born in Almada, Portugal in 1985. She received her Applied Chemistry Degree from the Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa in 2007. Presently she is working towards her M.Sc. degree in bioorganic chemistry under the supervision of Prof. Manuela Pereira at the same university. Her research is focused on ligand design and asymmetric organocatalysis.

Synthetic Study of 5‐Hydroxymethylfurfural in Groebke‐Blackburn‐Bienaymé Reaction

“…Finally, we studied the use of ytterbium triflate as a greener catalyst in the GBB multicomponent reaction. Ytterbium triflate is known to be a mild, versatile, and environmentally friendly Lewis acid catalyst [49,50] . Recent works highlight its usefulness in the GBB reaction [51,52] .…”

“…Ytterbium triflate is known to be a mild, versatile, and environmentally friendly Lewis acid catalyst. [49,50] Recent works highlight its usefulness in the GBB reaction. [51,52] Among the different conditions tested with this catalyst, the best results were obtained with the lowest temperature and catalyst loading (Table 1, entries [13][14][15][16]).…”
