Unlocking Free α-Trifluoromethoxy Carbene Reactivity from Aldehyde.
Carbenes, recognized as potent intermediates, enable otherwise inaccessible chemical transformations. The development of readily accessible aldehydes as oxycarbene precursors is of significant research value, yet it has never been achieved before. Compounds with a better decomposable trifluoromethoxy (-OCF3) group have...
