The effect of substituent on the regioselectivity of C-C bond cleavage has carefully been addressed by employing various ynones derivatives. The mechanism has been proposed for the observed regioselectivity.</p>10aC-C bond cleavage10aEsters10aKetones10ascandium triflate10aynones1 aKavthe, Rahul, D.1 aBansode, Avinash, H.1 aPatil, Nitin, T.  uhttps://library.ncl.res.in/content/scandium-triflate-catalyzed-unexpected-cleavage-c-c-bonds-ynones
