Development of new green strategies based on Brønsted and Lewis acid catalysis in organic synthesis

Environmental protection is one of the greatest themes of the XXI century. For what concerns chemistry, in the early 1990’s, even before its current formal and exhaustive definition, given by Paul T. Anastas and John C. Warner in 1998, the term "green chemistry" starts to appear in the literature. Anastas and Warner formulated a list of 12 principles, that constitute the most complete definition of green chemistry. Herein, an effort towards the fulfillment of these principles is presented with respect to: 1) the development of a catalytic system based on hydrate ferric sulfate for the hydration of internal alkynes; 2) an approach to the synthesis of a new family of chiral phosphates for organocatalysis.
