Diverse outcomes of CO fixation using alkali metal amides including formation of a heterobimetallic lithium-sodium carbamato-anhydride via lithium-sodium bis-hexamethyldisilazide. | LitMetric

AI Article Synopsis

  • The reaction of lithium amides made from pyrrole and diisopropylamine captures CO2, resulting in a lithium carbamate polymer and a dodecamer.
  • Using lithium-sodium hexamethyldisilazide leads to a complex reaction where the final product retains both lithium and sodium.
  • The resulting product features both carbamato and anhydride functional groups, which is unusual for this type of reaction.

Article Abstract

Fixation of CO2 by lithium amides derived from pyrrole and diisopropylamine generates a lithium carbamate polymer and dodecamer respectively. Moving to lithium-sodium hexamethyldisilazide produces a more complicated, intriguing reaction, where unusually the bimetallic composition is maintained in the product but its composition contains both carbamato and anhydride functionalities.
