Fluoroboric acid - Wikipedia
WebCarbocations can be prepared by mixing alcohols with a strong acid such as fluoboric acid (tetrafluoroboric acid); the fluoborate anion is a very weak nucleophile that doesn’t react with the resulting carbocation. You will prepare trityl fluoborate by the reaction of triphenylmethanol with 48% fluoboric acid. WebDay of Your Colonoscopy.
