Efficient synthetic methods towards mixed aliphatic carbonates through the three component couplings of aliphatic alcohols, alkyl halides and carbon dioxide in the presence of cesium carbonate and tetrabutylammonium iode (TBAI). Due to their enhanced nucleophilicities, cesium alkoxides are smoothly incorporated into CO.sub.2, allowing for mild reaction conditions such as ambient temperatures and short reaction durations. Various primary and secondary substrates are compatible under the standard conditions, offering high yields, while chiral templates such as .alpha.-hydroxy carbonyls are resistant to racemization.

Metodi sintetici efficienti verso i carbonati alifatici mixed attraverso i tre accoppiamenti componenti degli alcool alifatici, degli alogenuri alchilici e dell'anidride carbonica in presenza del carbonato del cesio e dello iode di tetrabutylammonium (TBAI). dovuto i loro nucleophilicities aumentati, alcossidi del cesio sono incorporati uniformemente in CO.sub.2, tenere conto la reazione delicata condiziona quali le temperature ambientali e le durate corte di reazione. I vari substrati primari e secondari sono compatibili nelle circostanze standard, rendimenti d'offerta di high, mentre le mascherine chiral quali i carbonilico alpha.-idrossilati sono resistenti alla racemizzazione.
