A convenient, metal-free intramolecular aminofluorination of alkenes has been developed. Employing readily available PhI(OPiv)(2) and hydrogen fluoride-pyridine in the presence of BF(3)·OEt(2), tosyl-protected pent-4-en-1-amines were converted to 3-F-piperidines in one step in good yields as well as high stereoselectivity.

Exposures of as little as 2.5 per cent of the body surface to concentrated hydrofluoric acid (HF) may be fatal. Survival after major HF exposures is facilitated by aggressive emergency management which, we feel, includes wound irrigation, subeschar injection of

Chemical burns sustained in the microelectronics industry consist mostly of injuries to the skin of the hand and face. The injuries are caused by splashes, holes in gloves, or accidental use of a chemical improperly. The chemical burns of the

Better understanding of the mechanism is important for exploring the potentials of a preconcentration method. In this work, we show for the first time that the HF etched porous junction on a fused silica capillary behaves not only as a

The carbonium ion has been suggested to be the intermediate in superacid-promoted reactions (SbF(5)-HF) such as hydrogen-deuterium exchange and in the electrophilic C-H cleavage into hydrogen and the carbenium ion. In this study, the superacid-promoted C-H cleavage into hydrogen and
