- (20) EXTRA: Propose a logical stepwise mechanism for the following reaction Bar in mind that the fluoride does things I) it forms a highly reactive symmetrical sol, and clectrophilic intermediate from the bere by attacking the trimethylsily group and chasing off the triflate in a 2 mechanism and 2) dieproces some of the ethyl acetoacetate allowing the emolate to react with the intermediate.
