On the Formation of Alcohols in the “Aprotic,” Alkaline Decomposition of Certain Aldehyde Tosylhydrazones^1,2

Rearrangement of 1-Noradamantyl and 1-Adamantylcarbene to Bridgehead Alkenes: Lifetimes of Two Bridgehead Carbenes in Solution

“…Kirmse et al prepared the 7,7-dimethyl derivative of 1 in solution and isolated the dimers of the strained alkenes . The Jones group prepared 1 - d 2 in the gas phase and isolated 4 - d 2 , which arose by retro-Diels−Alder fragmentation of alkene 2 . This result implies that the short bond of 1 migrates selectively, a result which has been successfully modeled by the calculations of Hadad and Sziemies and their co-workers.…”

“…Wilt attempted to generate the hydrocarbon variant of 1 from the tosylhydrazone salt precursor but was unable to identify carbene- or alkene-related products . Kirmse et al prepared the 7,7-dimethyl derivative of 1 in solution and isolated the dimers of the strained alkenes .…”

Structures of the cmphene sultones

“…From Fenchone. l,2,3,.-To an ethereal solution of methylmagnesium iodide, prepared from 225 g (1.7 moles) of methyl iodide and 47 g (1.95 g-atoms) of magnesium, was added 200 g (1.3 moles) of fenchone in ether. The mixture was refluxed for 2.5 hr and 150 ml of a saturated solution of ammonium chloride was slowly added.…”
