Title: | Activation of alkynes with [Cp*MCl2]2 (M=Rh or Ir) towards hydroamination reactions | Authors: | Kumaran Elumalai | Keywords: | DRNTU::Science::Chemistry | Issue Date: | 2014 | Source: | Kumaran Elumalai.

Doctoral thesis, Nanyang Technological University, Singapore. | Abstract: | Abstract Activation of alkynes for hydroamination reactions have been studied with the iridium and rhodium dimeric complexes [Cp*MCl2]2 (M=Rh or Ir). The reaction of [Cp*IrCl2]2, 1a with terminal alkynes and anilines afforded a variety of iridium amino-carbenes, whereas the rhodium analogue 1b gave a range of metallacycles. In the presence of additives, 1b was found to catalyse the hydroamination of alkynes with anilines to afford ketimines or 1,2-dihydroquinolines. Similarly, 1a could catalyse the hydroamination of 2-alkynylanilines to yield 2,2’-biindoles or indoles. The pathways for these reactions have been studied using a combination of experimental and computational methods. | URI: | https://hdl.handle.net/10356/58906 | DOI: | 10.32657/10356/58906 | Schools: | School of Physical and Mathematical Sciences | Fulltext Permission: | open | Fulltext Availability: | With Fulltext |
