Formation of 3-Oxa- and 3-Thiacyclohexyne from Ring Expansion of Heterocyclic Alkylidene Carbenes: A Mechanistic Study
[Image: see text] The rearrangement pathways of two alkylidene carbenes appended to an oxa or thiacyclopentane into the corresponding heterocyclohexynes were elucidated using (13)C-labeling experiments. Both carbenes exhibited a preference for migration of the allylic carbon bound to the heteroatom....
