The Relative Electrophilic Reactivities of Tropylium Cation and its (OC)3M ?-Complexes: Kinetic Studies of Alkoxide Transfer and Reversible Nucleophilic Addition

?-Complexation of the tropylium cation (Tr)(1+) with an (OC)3Cr group increases thermodynamic stability (ΔpKR+ ca. 4.3 in methanol) and reduces reactivity towards abstraction of methoxide ion from Malachite Green methyl ether (MG)OMe (krel. ca. 110) in MeNO2 - MeCOEt (40:60 v/v) and nucleophilic exoaddition of methanol (krel. ca. 2100) in methanol.The organometallic cation (1a) is stable in aqueous solutions of pH(1+), (1+), and (1+) in MeNO2-MeCOEt (40:60 v/v) are 1:10:6, respectively.The rates of transfer to (Tr)(1+) of alkoxide ion from (η-7-exo-alkoxycycloheptatriene)Cr(CO)3 complexes (2a-d) in MeCN decrease through the series: alkoxy=methoxy>ethoxy>isopropoxy>t-butoxy, but the overall rate change is only about five-fold.In methanol, the 7-exo-methoxycycloheptatriene complex (2a) is about ten times more reactive towards acid heterolysis than is methyl tropyl ether.This conversion is general acid-catalysed.In aqueous solutions of pH>ca. 6, the rate of spontaneous heterolysis of the ether (2a) is substantially faster than that of consumption of the resulting cation (1a) which increases with increasing pH.The 7-endo-methoxy stereoisomer (3) is inert to acid heterolysis in aqueous solutions to give cation (1a), but undergoes decomplexation to give (Tr)(1+).
