WebThis can be achieved with a base, such as triethylamine which will enable that the hydroxyl group functions as a nucleophile to attack the silicon atom and a chloride ion is expelled as a leaving group. The trimethylsilyl ether is formed via the reaction between an alcohol and trimethylsilyl chloride, abbreviated TMSCl. WebA triflate group is an excellent leaving group used in certain organic reactions such as nucleophilic substitution, Suzuki couplings and Heck reactions. Since alkyl triflates are …

Weak bases have strong conjugate … i keep dancing on my own calum scottWebIn our general discussion of nucleophilic substitution reactions, we have until now been designating the leaving group simply as “X”. As you may imagine, however, the nature of the leaving group is an important consideration: if the C-X bond does not break, the new bond between the nucleophile and electrophilic carbon cannot form, regardless of … i keep dancing with the lights onWebNext SectionSilyl Ether Protecting Groups. One way to protect alcohol is to form a reversible adduct with isobutylene via acid-catalyzed alkoxylation, yielding a temporary tert-butyl ether, which is completely unreactive.
