The products of the Stevens 3,2-rearrangement of ammonium salts containing methyl and other (ethyl, propyl, butyl) alkyl groups along with 3-phenylprop-2-ynyl, under the reaction conditions undergo, roughly by half, intramolecular hydride shift with inter
Intramolecular 1,5-hydride shift in products of stevens 3,2-rearrangement of ammonium salts containing 3-phenyl-2-propynyl group

In products of Stevens 3,2-rearrangement of ammonium salts containing alongside alkoxycarbonylmethyl also 3-phenyl-2-propynyl group an intramolecular 1,5-hydride shift is observed resulting in immonium salts which transform into aminoesters of enamine str

The propynylammonium salt (5) reacts with aqueous sodium hydroxide to give the allene (7) and a new ylide (11).The simultaneous formation of (7) and (11) suggests that the apparent sigmatropic rearrangement of the propynyl ylide (6) to the allene (7
