Synthesis, Characterization and Catalytic Study of a Novel Binuclear Paddle-wheel Palladium(II) Complex in the Mizoroki-Heck Reaction
A new binuclear paddle-wheel palladium(II) complex of [Pd2(μ-mtzt)4]dmgH2 (1) has been prepared by the treatment of PdCl2 in acetonitrile with mixture of 1-methyl-1H-1,2,3,4-tetrazole-5-thiol (Hmtzt) and dimethylglyoxime (dmgH2) in methanol. Resulted complex was characterized by elemental analysis (CHNS), IR, UV–Vis absorption, 1H NMR spectroscopy and its structure was determined with single-cr...
متن کاملSynthesis, Characterization and Catalytic Activity of Ligand Stabilized Palladium Nanoparticle: A Catalyst Compliment to the Heck Coupling Reaction
The palladium metal is the most frequently used metal because of its excellent catalytic efficiency and most flexible varying oxidation state. So, we report that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L) using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and...
متن کاملMechanisms of the Mizoroki–Heck Reaction
The palladium-catalysed Mizoroki–Heck reaction is the most efficient route for the vinylation of aryl/vinyl halides or triflates. This reaction, in which a C C bond is formed, proceeds in the presence of a base (Scheme 1.1) [1, 2]. Nonconjugated alkenes are formed in reactions involving cyclic alkenes (Scheme 1.2) [1e, 2a,c,e,g] or in intramolecular reactions (Scheme 1.3) [2b,d–g] with creation...
