    1. Lintho tse ngata tsa cesium carbonate ka har'a motsoako oa lintho tse phelang li tsoa ho Lewis acidity e bonolo ea cesium ion, e etsang hore e qhibilihe ka har'a li-solvents tse kang joala, DMF le ether.

    2. The hantle solubility ka solvents manyolo nolofalletsa cesium carbonate e le e atlehang inorganic botlaaseng ho nka karolo karabelong ea lik'hemik'hale catalyzed ke palladium reagents tse kang Heck, Suzuki le Sonogashira reactions. Ka mohlala, karabelo ea Suzuki cross-coupling e ka finyella lihlahisoa tsa 86% ka tšehetso ea cesium carbonate, ha lihlahisoa tsa karabelo e tšoanang le ho kenya letsoho ha sodium carbonate kapa triethylamine ke 29% feela le 50%. Ka mokhoa o ts'oanang, ts'ebetsong ea Heck ea methacrylate le chlorobenzene, cesium carbonate e na le melemo e totobetseng ho feta metheo e meng e sa tloaelehang, e kang potassium carbonate, sodium acetate, triethylamine, le phosphate potassium.
