Both nucleophiles were synthesized via sequential palladium-catalyzed couplings starting from trimethylsilylacetylene and an aryl bromide (ethyl p-bromobenzoate for I and butyl p-bromobenzenesulfonate for II). After desilylation, a second palladium-catalyzed coupling was completed with another aryl bromide (butyl p-bromobenzenesulfonate for I and p-bromophenyl acelate for II). Deprotection led to salts of I and II.

No correction was made for mass descrimination. In the narrow mass range of interest (m/z = 270-330), test studies suggest that mass descrimination has only a minor effect.

The reactions of I are about an order of magnitude slower than those of II. With the present experimental setup, it was not possible to hold I in the trap long enough to allow for a sufficent number of half-lives in its reactions.
