Fluoride environmental sources

Farooqi, A., Masuda, H. and Firdous, N. (2007) Toxic fluoride and arsenic contaminated groundwater in the Lahore and Kasur districts, Punjab, Pakistan and possible contaminant sources. Environmental Pollution, 145(3), 839-49. 

Lentz and coworkers reported that air-stable titanocene difluoride can act as a catalyst for hydrodefluorination reactions in the presence of silane derivatives, giving excellent yields even at low temperature. The authors expanded the scope of the reaction to other substrates such as vinylic and allylic fluorides and a range of catalysts.Mechanistic studies indicated that a titanium(m) hydride is the active species, and the silane derivative is the hydride source. This catalytic system is not only interesting form the environmental point of view, but also for the synthesis of new organic molecules as it represents a new synthetic route to obtain inaccessible aminopyridine derivatives." ...
