An efficient electrochemical synthesis of 5-methylene-1,3-oxazolidin-2-ones (2a−h) fromacetylenicamines (1a−h) and carbon dioxide has been achieved by direct electrolysis of solution of MeCN and Et4NPF6 containing the amine, with subsequent CO2 bubbling and heating. The yields vary from good to excellent, the conditions are mild, and the use of toxic and harmful chemicals and catalysts is avoided
的5-亚甲基-1,3-恶唑烷-2-酮(一种有效的电化学合成2A - ħ从炔胺()1A - H ^)和二氧化碳已经通过的MeCN和Et的溶液直接电解来实现4 NPF 6含有胺,随后鼓入CO 2并加热。收率各有不同,条件温和,避免使用有毒有害的化学物质和催化剂。
