Reductive Pauson-Khand reaction using the (RC≡CR′) Co2(CO) 6/CF3COOH system
Rao, M. Lakshmi Narayana,Periasamy, Mariappan
, p. 143 - 146 (1997)
Cyclopentanones are formed in the Pauson-Khand reaction of cobalt alkyne complexes in the presence of TFA. The in situ precursor complexes were formed on the reduction of CoBr2 by zinc metal in the presence of the alkynes under carbon monoxide
Heterobimetallic alkyne complexes inorganic synthesis: An asymmetric variant of the Pauson-Khand reaction
Rutherford, David T.,Christie, Steven D. R.
, p. 9805 - 9808 (2007/10/03)
The use of heterobimetallic alkyne complexes for the synthesis of cyclopentenones is described. The inherent chirality of the complexes has been used to effect high levels of stereocontrol in transformations giving optically enriched organic end products.
Simple, Convenient Methods for the Preparation of Alkyne-Co2(CO)6 Complexes from CoBr2 for Application in Pauson-Khand Cyclopentenone Synthesis
Periasamy, Mariappan,Reddy, Malladi Rama,Devasagayaraj, Arokiasamy
, p. 6955 - 6964 (2007/10/02)
Alkyne-dicobalthexacarbonyl complexes are readily prepared by the reduction of cobalt bromide by Zn in the presence of alkynes in THF while bubbling carbon monoxide under ambient conditions.The complexes prepared in this way react with olefins to give the
A SIMPLE CONVENIENT SYNTHESIS OF ALKYNE-Co2(CO)6 COMPLEXES AND THEIR UTILIZATION IN THE PAUSON-KHAND CYCLOPENTENONE SYNTHESIS
Devasagayaraj, A.,Periasamy, M.
, p. 595 - 596 (2007/10/02)
Reduction of anhydrous CoBr2 in THF with Zn under carbon monoxide atmosphere at room temperature followed by treatment with alkynes gives the corresponding alkyne-cobalt carbonyl complexes, which on reaction with olefins give the corresponding cyclopenten
