Oxidative rearrangement of alkynes to carboxylic acid esters by [hydroxy(tosyloxy)iodo]benzene in methanol was written by Moriarty, Robert M.;Vaid, Radhe K.;Duncan, Michael P.;Vaid, Beena K.. And the article was included in Tetrahedron Letters in 1987.Safety of Methyl 2-thienylacetate This article mentions the following:
RR1CHCO2Me (I; R = Pr, Bu, Ph, C6H4Ac-4, thienyl; R1 = H, Me, Et) were prepared by oxidative rearrangement of RCCR1 with [hydroxy(tosyloxy)iodo]benzene in MeOH. Hydrolysis of I gave RR1CHCO2H. In the experiment, the researchers used many compounds, for example, Methyl 2-thienylacetate (cas: 19432-68-9Safety of Methyl 2-thienylacetate).
Methyl 2-thienylacetate (cas: 19432-68-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Safety of Methyl 2-thienylacetate
