Iona, Roberto; Bassetti, Mauro published the artcile< Dimerization of Aromatic Terminal Alkynes Featuring Hydrophilic Functional Groups under Ruthenium and Acid Promoted Catalysis. Competitive Alkyne Hydration upon Substituent Effect>, Formula: C9H8O, the main research area is dimeric diarylenyne stereoselective preparation; aryl terminal alkyne hydrophilic functional group dimerization ruthenium catalyst.
The self-coupling (hydroalkynylation) process of aromatic terminal alkynes RC6H4CCH to give dimeric 1,4-diaryl-1-en-3-yne products (trans-RC6H4CCCH=CHC6H4R) is catalyzed by the complex [{RuCl(μ-Cl)(η6-p-cymene)}2] with sodium acetate co-catalyst dissolved in neat acetic acid, the reaction proceeding with high trans-stereoselectivity under mild conditions (r.t.) even for substrates with protic or polar substituent groups (e. g. R = 3-OH, 4-CH2OH, 4-NHAc, -CHO, 4-tetra-O-acetyl-β-D-glucopyranoside). In presence of strongly electron donating arene substituents, NMe2 and NH2, the triple bond is activated toward exclusive triple bond hydration by reaction with acetic acid at room temperature also in absence of the ruthenium catalyst.
