Halogen chemistry.

A large number of halogenated organics have been produced commercially in the past few decades, which have been used for a variety of purposes. The quest for enviromentally friendly technology in general has risen to a substantial thrust to get away from chlorocarbons and halogenated materials altogether, due to the generic deleteriousness associated to them. Halogenated compounds continue to be produced and utilized, however, as they still remain both the best solvents for some high-tech processes and flexible starting materials for a variety of organic syntheses.
