The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium(SMILESS: CC1=C([P]2([Pd+2]3([CH2-]C4=C2C=CC=C4)[O-]/C(C)=O[Pd+2]5([O-]/C(C)=O3)[P](C6=C(C)C=CC=C6)(C7=C([CH2-]5)C=CC=C7)C8=C(C)C=CC=C8)C9=C(C)C=CC=C9)C=CC=C1,cas:172418-32-5) is researched.Electric Literature of C6H8ClN3. The article 《Synthesis and Characterization of N-Heterocyclic Carbene Phospha-Palladacycles and Their Properties in Heck Catalysis》 in relation to this compound, is published in Organometallics. Let’s take a look at the latest research on this compound (cas:172418-32-5).
Cyclopalladated 2-phosphinobenzyl imidazolylidene and tetrazolylidene complexes were prepared by complexation of the N-heterocyclic carbene ligand with palladium cyclometalated dimer; the complexes exhibit high catalytic activity in Heck arylation of styrene, producing trans-stilbenes. Reaction of 1,3-R42-imidazolylidene or 2,4,5-triphenyl-1,2,4-triazol-3-ylidene (NHC) with [Pd(CH2C6H4-2-PR2R3-κP)X]2 afforded monomeric cyclopalladated complexes [Pd(CH2C6H4-2-PR2R3-κP)(NHC)X] (3-10; R2, R3 = o-tolyl, tBu, cyclohexyl; X = OAc, Br; R4 = 1-adamantyl, tBu, mesityl); analogous reaction afforded [Pd(CH2C6H4-3,5-Me2-2-PMes2-κP)(IMes)Br] (11; Mes = 2,4,6-Me3C6H2; IMes = 1,3-Mes2-imidazol-2-ylidene) and [Pd(CH2C6H4-3,5-Me2-2-PMes2-κP)(TPT)(OAc)] (12; TPT = 2,4,5-triphenyl-1,2,4-triazol-3-ylidene). Bis-N-heterocyclic cationic complexes were prepared by reaction of the palladium dimer with excess of the NHC. Palladacycles are among the most active catalyst systems for the Mizoroki-Heck reaction to date. The new type of palladacycle N-heterocyclic carbene complexes combines the advantageous stability of phospha-palladacycles with the steric demand and high σ-donor strength of N-heterocyclic carbenes. Some of the prepared complexes were tested as catalysts for Heck arylation of styrene, producing substituted trans-stilbenes in moderate to good yields and good stereoselectivities. The activity of these catalysts allows the coupling of even aryl chlorides in good yields.
