Halide and Amine Influence in the Equilibrium Formation of Palladium Tris(o-tolyl)phosphine Mono(amine) Complexes from Palladium Aryl Halide Dimers
TL;DR: In this paper, the relative binding constants for amines to the palladium fragment Pd[P(o-tol)3](p-C6H4Me)Cl were determined by 1H NMR spectroscopy and decrease in the order hexylamine > benzylamine ≈ cyclohexylamines ≈ piperidine > dibutylamine etc.

TL;DR: The solution behavior of the cationic complexes [Pd(η3-allyl)(P−N)]+ (Pd = o-(PPh2)C6H4CHNR (R = C6H 4OMe-4, Me, CMe3, (R)-bornyl); allyl = propenyl (1a−4a) and 3-methyl-2-butenyl(1b−4b)) consists essentially of three dynamic processes: a very fast conformational change of the P−N chelate ring

Selectivity in palladium catalysed allylic substitution
TL;DR: Palladium catalysed allylic substitution has emerged as one of the more useful synthetic methods for the construction of C-C and C-X bonds as mentioned in this paper, which offers the advantages of mild reaction conditions, as well as the ability to accomodate a wide range of nucleophiles and their electrophilic partners.
