**Ion cyclotron resonance measurements on D‐labeled furan** revealed that in the prototype electrophilic reactions—__i.e.__ protonation—furan behaves in the gas phase as a typical arene and not as enol ether.
Experimental procedure: 2 : 30% H 2 0 2 (11.3 g, I00 mmol) was added with stirring to ethyl pyruvate (17.3 g, 150 mmol) at -10 to 0°C [3]. This solution was then added with stirring and cooling (-5 to 0°C) to a mixture of I (10 mmol), conc. H S O J (3 g), H 2 0 (8g), F e S 0 4 . 7 H 2 0 (28 g, 100mm
## The isobutane chemical ionization (CI) mass spectra of cis-and trans-1-butyl-3-and -4-dimethylaminocyclohexanols and of their methyl ethers exhibit abundant [MH -H 2 O] Y and [MH -MeOH] Y ions respectively. On the other hand, only the MH Y ions of the cis-isomers exhibit significant [MH -H 2 O]
