(21) Coordination of Ag+ to phthalazine in the presence of 2,2′-
bipyridine was investigated by 1H and 13C NMR experiments. See the

(22) N−Si interactions may play a role in the activation of siloxy
alkynes. We thank one of the reviewers for suggesting this possibility.
(23) Mild Brønsted acids promote a different cycloaddition reaction
between phthalazines and siloxy alkynes. These findings will be
reported in due course.
