We report herein a simple, efficient strategy to access diverse end-functionalized polymers from a living ring-opening metathesis polymerization process using diazoacetates as a new terminating agent. Such a terminating process occurs via a C=C bond-forming reaction between the chain-end ruthenium carbenes and the diazoacetates, resulting in the rapid construction of a unique, α,β-unsaturated carbonyl motif at more than 95% of the chain end within 5 min. A variety of easily accessible and diversely substituted diazoacetates could be used, allowing for the facile introduction of an addnl. panel of useful functionalities at the polymer chain end. Diverse postpolymn. modifications, including Michael addition, “click” reaction, and chain extension, have been further demonstrated. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Computed Properties of C10H20O).
(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Computed Properties of C10H20O
