Solvent effects in the reaction between (anthracen-9-yl)methyl sulfides and electron-deficient acetylenes
Solvent-dependent diverse reactivity of (anthracen-9-yl)methyl sulfides with a few electron-deficient acetylenes is described. Diversity in reactivity is attributed to competition between one electron transfer, two electron transfer and Diels-Alder reaction of these sulfides with electron-deficient acetylenes. We have proposed plausible mechanisms to account for various reactions observed by us.
