New insights into cyclopropanation: application in the synthesis of a novel high-heating-value hydrocarbon fuel derived from furfural†
Abstract
Cyclopropanation is crucial in synthesizing high-heating-value fuels. In situ experiments and computational studies provide new insights into the four-step cyclopropanation, where the high activity of Al carbenoid is attributed to the electron shift from olefin to Al carbenoid and high proximity of Al carbenoid with olefin.
