<b>Vinyltriphenylphosphonium salt-mediated preparation of thiophene-containing electron-poor alkenes from acetylenic esters, 2-thienylmethanol and triphenylphosphine</b>
Protonation of the highly reactive 1:1 intermediates, produced in the reaction between triphenylphosphine and alkyl acetylenecarboxylates (methyl acetylenecarboxylate, ethyl acetylenecarboxylate and ethyl phenylacetylenecarboxylate) by 2-thienylmethanol leads to vinyltriphenylphosphonium salts, whic...
