Pramanik, Milan published the artcilet-BuOLi-promoted terminal alkyne functionalizations by aliphatic thiols and alcohols, SDS of cas: 4410-99-5, the publication is Organic & Biomolecular Chemistry (2022), 20(13), 2671-2680, database is CAplus and MEDLINE.
Selective addition of aliphatic thiols or alcs. R1XH (X = O, R1 = Me, Et, F3CCH2, n-decyl, etc.; X = S, R1 = i-Bu, PhCH2, n-dodecyl, 2-furylmethyl, etc.) to N-aryl propiolamides HCCC(O)NHR2 (R2 = Ph, 2-MeC6H4, 3,4-Cl2C6H3, etc.) using lithium tert-butoxide in ethanol as a promoter is described. Mechanistically, it was shown that the reaction proceeds through the generation of a thiyl radical intermediate, and the amide group in N-phenylpropiolamide helps in the activation of the alkyne, which led to thioacetalization via the formation of a (Z)-selective anti-Markovnikov vinyl sulfide. The (Z)-selectivity during the formation of vinyl sulfides was controlled by an intramol. sulfur···oxygen interaction.
