“…Pearson's concept of "hard" and "soft" acids and bases (HSAB) [86,87] is very useful for explanation of problems of coordination chemistry [87,88] and catalysis with participation of transition metal complexes [86,[88][89][90]. It is clearly visible that hardness of metal atom and ligand (solvent or Q-allyl) has a great significance for course of the reaction between Q-allyl and ruthenium complexes.…”

Synergistic catalysis: A powerful synthetic strategy for new reaction development

Synergistic catalysis is a synthetic strategy wherein both the nucleophile and the electrophile are simultaneously activated by two separate and distinct catalysts to afford a single chemical transformation. This powerful catalysis strategy leads to several benefits, specifically synergistic catalysis can (i) introduce new, previously unattainable chemical transformations, (ii) improve the efficiency of existing transformations, and (iii) create or improve catalytic enantioselectivity where stereocontrol was previously absent or challenging. This perspective aims to highlight these benefits using many of the successful examples of synergistic catalysis found in the literature.

2005)Ring-opening polymerization of cyclohexene oxide by a novel dicationic palladium catalyst, Designed Monomers and Polymers, 8:6,[571][572][573][574][575][576][577][578][579][580][581][582][583][584][585][586][587][588] To link to this article: http://dx.Abstract-The synthesis of a novel, air-and moistures table dicationic palladium (II) complex, Pd(CH 3 CON-(2-pyridyl) 2 )(CH 3 CN) 2+ 2 (PF − 6 ) 2 (1) is described. 1 crystallizes in the mononoclinic space group C2/m, a = 2391.11(4), b = 1063.34(5), c = 1137.59(6) pm, α = 90 • , β = 105.026(2) • , γ = 90 • , Z = 4. Its use in the ring-opening polymerization (ROP) of cyclohexene oxide in comparison to the parent catalyst, dichloropalladium di(pyrid-2-yl)amide (2) was investigated. In contrast to 2, 1 shows excellent reactivity in the ROP of cyclohexene oxide, allowing a class-II living polymerization, however, it fails to polymerize propylene oxide.
