14. 4. The phenomenon of cocrystallization of acid in the isolation of diplatinum(III) complexes has been observed previously: Peilert, M.; Weissbach, S.; Freisinger, E.; Korsunsky, V. I.; Lippert, B. Inorg. Chim. Acta 1997, 265, 187. Safety note: Although we have not had any problem in using perchloric acid, the acid is known to be potentially explosive, especially when mixed with organic compounds and heated. Great caution should be exercised while handling it.

17. 2O at ambient temperature gave 3-methoxy-1-cycloolefins along with trace amounts of cycloolefins and a small amount of unidentified products, indicating that β-H elimination is a predominant process over nucleophilic attack in the presence of base.
