Protic and substituted NCN palladium(II) pincer complexes with 1,3-bis(benzimidazol-2?-yl)-2-bromobenzenes: Structure and catalysis
A new class of sparingly soluble NCN palladium(II) pincer complexes of the type (N?C?N)PdBr: [Methyl(N?C?N)PdBr], C26H25N4PdBr (14), [Tosyl(N?C?N)PdBr], C38H33N4O4S2PdBr (15), [Benzyl(N?C?N)PdBr], C38H33N4PdBr (16) and [Pentyl(N?C?N)PdBr], C34H41N4PdBr (17) [(N?C?N) = 5-tert-butyl-1,3-bis-(N-substituted-benzimidazol-2?-yl)phenyl] were synthesized by the treatment of palladium(0) precursor, Pd2(dba)3 with 5-tert-butyl-1,3-bis-(N-substituted-benzimidazol-2?-yl)-2-bromobenzenes (10?13) via oxidative addition with chemical yield of 46?70%. Complex 15 decomposed in [D6]DMSO to yield the protic palladacycle 18, [H(N?C?N)PdBr], C24H21N4PdBr, which was confirmed by the time-dependent 1H NMR studies, IR spectroscopy, mass spectrometry and the structure was corroborated with X-ray crystallographic studies. Complexes 14?18 are the fully characterized examples of NCN palladium(II) pincer complexes incorporating the N-substituted-5-tert-butyl-1,3-bis-(benzimidazol-2?-yl)-2-bromobenzene framework. The palladium(II) pincer complexes have been studied for C-H functionalization of benzyl nitriles with N-tosylaldimines to form beta-aminonitriles.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C51H42O3Pd2, you can also check out more blogs about52409-22-0
