ERIRA D, Edith M  e  FADINI, Luca. IONIC LIQUID APPLICATION IN THE HOMOGENOUS HYDROAMINATION OF OLEFINS CATALYZED BY Ni(II). Rev.Colomb.Quim. [online]. 2008, vol.37, n.3, pp.317-324. ISSN 0120-2804.

Ionic liquids are excelent solvents for catalytic reactions because they can optimize and/or recycle the homogeneous catalysts. In this work we describe the use of ionic liquids with low melting point (-30 – -34 °C) –based on pyridine derivatives– in the hydroamination reaction of activated olefins catalyzed by Ni(II) complexes. The catalyst [Ni(Pigiphos) (NCCH3)](ClO4)2 allows good activity in ionic liquids (TON up to 172) and the catalyst/ ionic liquid system can be recycled at least 2 times.

Palavras-chave : ionic liquids; homogeneous catalysis; hydroamination; nickel( II); green chemistry; Pigiphos.
