Related Products of 21797-13-7, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 21797-13-7, Name is Tetrakis(acetonitrile)palladium(II) tetrafluoroborate, molecular formula is C8H12B2F8N4Pd.

1,2,4,5-Tetrakis(phenyselenomethyl)benzene (L) has been synthesized by reaction of in situ generated PhSe- with 1,2,4,5- tetrakis(bromomethyl)benzene in N2 atmosphere. Its first bimetallic complexes and a bis-pincer complex having compositions [(eta3- C3H5)2Pd2(L)][ClO4] 2 (1) [Pd2(C5H5N) 2(L)][BF4]2 (2) and [(eta6-C 6H6)2Ru2(L)Cl2][PF 6]2 (3) have been synthesized by reacting L with [Pd(eta3-C3H5)Cl]2, [Pd(CH 3CN)4][BF4]2 and [(eta6-C6H6)2RuCl 2]2 respectively. The structures of ligand L and its all three complexes have been determined by X-ray crystallography. In 1 and 3, ligand L forms with two organometallic species seven membered chelate rings whereas in 2 it ligates in a bis-pincer coordination mode. The geometry around Pd in 1 or 2 is close to square planar whereas in 3, Ru has pseudo-octahedral half sandwich “Piano-Stool” geometry. The Pd-Se bond distances are in the ranges 2.4004(9)-2.4627(14) A and follow the order 1 > 2, whereas Ru-Se bond lengths are between 2.4945(16) and 2.5157(17) A. The 1 and 2 have been found efficient catalysts for Heck reaction of aryl halides with styrene and methyl acrylate. The 2 is superior to 1. The TON and TOF values (per Pd) are up to ? 47500 and ?2639 h-1 respectively. The Royal Society of Chemistry 2010.
