Pyrylium Mediated Transformations of Neopentylamine

Katritzky, Alan R.,Singh, Jagadish N.

, p. 421 - 424 (2007/10/02)

A series of 2,4-diphenyl-5,6-dihydrobenzochromenylium salts have been prepared.They react with neopentylamine to form the corresponding 1-neopentylquinolinium salts which on thermolysis afford neopentyl halides, trifluoracetate, and thiocyanate, in good yields without rearrangements.
