A recyclable AgI/OAc- catalytic system for the efficient synthesis of α-alkylidene cyclic carbonates: carbon dioxide conversion at atmospheric pressure

The cyclization of carbon dioxide and propargylic alcohols, especially challenging substrates, were efficiently catalyzed by a green and recyclable AgI/OAc- system under atmospheric pressure, which is shown to be the most recyclable system with 20 recycle rounds and has the lowest loading among all the reported recyclable systems that work under atmospheric pressure.
