Abstract
The decrease in chemical shift of the vinylic protons of cyclohexene with increasing silver(I) salt concentration indicates that extent of olefin π-complexation to silver salt decreases in the order silver trifluoromethanesulfonate > silver hexafluoroantimonate > silver tetrafluoroborate. Proton NMR analysis shows that alkynes π-complex nearly as well as olefins to silver trifluoromethanesulfonate. Silver trifluoromethanesulfonate π-complexes of monoenes, dienes, trienes, monoynes, and diynes have been prepared and isolated. All complexes are 1 : 1 in the solid state and solution, and all carbon—carbon multiple bonds are coordinated to silver ion. Stability constants measured by proton NMR for the alkyne—silver trifluoromethanesulfonate complexes decrease in the order 1,8-cyclotetradecadiyne > 3-hexyne > 2-hexyne > 4-methyl-2-pentyne.
