5, 25 g in glass bottle

Application

Ytterbium(III) trifluoromethanesulfonate hydrate (Yb(OTf)3) was employed as Lewis acid catalyst for the following studies:
• Synthesis of the dihydropyrimidine (DHPM) derivative monastrol, by Biginelli cyclocondensation.
• Cross-aldol reaction between ketone and aldehyde.
• Synthesis of β-keto enol ethers.
• Synthesis of deoxypenostatin A in a novel, stereoselective intramolecular Diels-Alder reaction.

General description

Layer-by-layer assembly of 4-aminothiophenol and ytterbium(III)trifluoromethanesulfonate hydrate film has been investigated by atomic force microscopy (AFM). Bis(oxazolinyl)-pyridine-scandium(III) triflate complexes have been reported to catalyze the enantioselective Friedel-Crafts addition of various indoles.

Friedel–Crafts Acylation

The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form m...
