Abstract

We report a facile, one-step green synthesis of two new star-shaped compounds containing three or six pendant carbonate groups with terminal alkynes. The reaction occurs under 1 atm CO₂ and proceeds optimally at room temperature. These multialkynyl-carbonate-functionalized benzenes represent readily accessible precursors to more complex dendritic materials.
