TL;DR: The dinuclear dihydrido iridacyclopentadienyl complex η5[1-(η4-cod)-1,1-H2-IrCHCHCH-CH]-(η 4-cod)Ir (1) was obtained by reaction of [(diene)MCl]2 with the corresponding butenediylmagnesium reagents in tetrahydrofuran as mentioned in this paper.

TL;DR: In this article, cyclic voltammetry (Pt electrode) and polarography at the DME were used to determine the one electron reduction of cations [NiCpL 2 ] + (Cp = η 5 -cyclopentadienyl, L = PR 3, P(OR) 3 or L 2 = 1,5-cyclooctadiene, norbornadiene and bis(diphenylphosphino)ethane.

TL;DR: In this paper, the effect of aryl substituents on the thermal reversion was investigated and it was shown that spin delocalization and polar effect equally contribute to the stabilization of the transition state.
Abstract: 2-Arylhexachloronorbornadiene undergoes photoisomerization to the corresponding quadricyclane, which returns back to the norbornadiene upon heating without catalyst Effect of aryl substituents on the thermal reversion suggests that both spin delocalization and polar effect equally contribute to the stabilization of the transition state

TL;DR: In this paper, an experimental and computational approach was employed to study the mechanisms of the palladium-promoted hydroalkynation and [2+1] cycloaddition, which may have important implications for other palladiumcatalyzed transfor- mations especially those involving phosphapalladacycles and phosphinous acid-phosphinito-containing palladium complexes.
Abstract: Whereas the reaction of norbornadiene with terminal alkynes in the presence of a phosphapalladacycle catalyst leads to the formation of hydroalkynation products, the use of phosphinous acid–phosphinito-containing palladium complexes gives rise to formal [2+1] cycloadducts. An experimental and computational approach was employed to study the mechanisms of the palladium-promoted hydroalkynation and [2+1] cycloaddition. On the one hand, experiments highlight the crucial role of acidolysis steps on the catalytic activities. On theother hand, DFT calculations demonstrate the specificity of the phosphinito–phosphinous acid ligands, that is, the non-equivalence of the two phosphorus atoms but the interchangeability of their properties. These results may have important implications for the mechanism of other palladium-catalyzed transfor- mations especially those involving phosphapalladacycles and phosphinous acid–phosphinito-containing palladium complexes
