Transition metal alkyne complexes: the Pauson–Khand reaction
TL;DR: The Pauson-Khand reaction (PKR) is a cocyclization of alkynes with alkenes and carbon monoxide by dicobalt octacarbonyl leading to cyclopentenones.

S. T. Ingate,J. Marco-Contellers +1 more
TL;DR: A review of the ASYMMETRIC PAUSON-KHAND reaction can be found in this paper, with a focus on the Asymptotic Puson-Khand reaction.
Book ChapterDOI
The Pauson–Khand Reaction
TL;DR: The Pauson-Khand cycloaddition reaction was first reported in detail by Khand et al. as discussed by the authors in 1973 and has been used extensively in the subsequent half-dozen years or so.
Journal ArticleDOI
Pauson−Khand Reactions of Electron‐Deficient Alkenes
TL;DR: Despite the common perception that alkenes possessing electron-withdrawing groups are not adequate substrates for Pauson−Khand (PK) reactions, a number of successful examples of this reaction involving electron-deficient alkenses, such as α,β-unsaturated ketones, esters, nitriles, sulfoxides and sulfones, have been reported in recent years as discussed by the authors.
Book ChapterDOI
Cycloadditions onto methylene- and alkylidenecyclopropane derivatives
TL;DR: In this paper, all the reactions which involve the exocyclic double bond of alkylidenecyclopropanes in cycloaddition processes are dealt with.

The khand reaction : A convenient and general route to a wide range of cyclopentenone derivatives
TL;DR: In this paper, the formation of cyclopentenones from alkynes, plus alkenes and cobalt carbonyl is reviewed, with special attention to the scope and the regio- and stereoselectivity of the reaction.

Origins of 1,2- and 1,3-Stereoselectivity in Dicobaltoctacarbonyl Alkene-alkyne Cyclizations for the Synthesis of Substituted Bicyclo[3.3.0]octenones.
TL;DR: In this paper, a working mechanistic hypothesis is proposed which rationalizes the stereochemical outcome of the synthesis of substituted bicyclo[3.3.O]octenones, using dicobaltoctacarbonyl mediated alkene-alkyne cyclizations.
