Abstract
Conclusions The unique capability of NRMS for preparation and study of unusual neutral species has been utilized to demonstrate the surprising stability of the simple ylides H2CYH, 1-4. Unless these represent metastable states of unusually long lifetimes, this indicates that ab initio calculations overestimate AH, values for such hypervalent species. A better understanding of the (H2C)-(YH) bonding underlying this stability could be valuable in ...
