The 1,3 ene-yne functionality is an important synthon towards complex products, as well as a common functionality in biologically active molecules. Here, we present a new synthetic route towards fluorinated ene-ynes from simple starting materials. We employ gas chromatography-mass spectrometry analysis to probe the sequential eliminations necessary for this transformation and observe an allene intermediate. The ene-yne products are sufficiently fluorous to enable purification via fluorous extraction. This methodology will allow facile access to functional, fluorous ene-ynes. Key words Key wordsfluorous - ene-yne - allene - sequential elimination Full Text References References 1 Wang J, Sánchez-Roselló M, Aceña JL, Del Pozo C, Sorochinsky AE, Fustero S, Soloshonok VA, Liu H.
