Binuclear Orthometalated N,N-Dimethylbenzylamine Complexes of Palladium(II): Synthesis, Structures and Thermal Behavior

Cyclopalladation of dimesityl selenide: synthesis, reactivity, structural characterization, isolation of an intermediate complex with C–H⋯Pd intra-molecular interaction and computational studies

“…This type of interaction is absent in 3b. 32 The Pd⋯Pd distance in 3a (2.9288(9) Å) is within the generally acceptable range of intra-molecular Pd⋯Pd interactions (<3.00 Å), while in the corresponding selenolate complex (3b) it is much longer (3.143 Å). In complex 3a, one of the mesityl rings on both the selenium ligands are parallel to each other and are separated by 3.587 Å, which may be attributed to π-stacking, and are positioned on the opposite side of the pyridine thiolate rings.…”

“…The 1 H NMR spectrum of 3b was quite complex due to the existence of other isomeric species in solution which were also corroborated by the 77 Se NMR spectrum, which displayed resonances attributable to two isomeric forms (sym-cis and sym-trans). However, only one isomeric form could be crystallized 32,33 are known to adopt different isomeric forms and in solution, a dynamic equilibrium may exist between them. 33 The molecular structures of 1, 2, 3a and 3b, established by X-ray diffraction analyses, are shown in Fig.…”

Structural Variation in [PdX2{RE(CH2)nNMe2}] (E = Se, Te; X = Cl, OAc) Complexes: Experimental Results, Computational Analysis, and Catalytic Activity in Suzuki Coupling Reactions

“…The Pd–N distance in 2e , however, is much longer (2.210 Å). This is in accordance with the distances reported in compounds that contain a nitrogen atom trans to strong trans ‐influencing ligands (e.g., [PdI(SeC 6 H 4 CH 2 NMe 2 ‐2)(PPh 3 )] [Pd–N = 2.1958(18) Å];30 [Pd 2 (μ‐Sepy) 2 (Me 2 NCH 2 C 6 H 4 ‐ C , N ) 2 ] [Pd–N = 2.189(8) Å]31. The Pd–Se (ca.…”

Facile and Efficient Access to Tetrahydrobenzo[b]pyrans Catalyzed by N,N-Dimethylbenzylamine

“…42,43 This tert-amine was also used as the directing group to ortho-functionalizations such as, ortho arylation, 44 ortho olefination, 45 borylation of arenes, 46 ortho carbonylation, 47 and ortho-silylation. 44 It is noteworthy to mention that the N,N-dimethylaminomethyl group present in the functionalized N,N-dimethylbenzylamines can be easily converted to various and useful functional groups including, amide, 48 aldehyde, 49 alkene, 50 as well as chloromethyl substituent.…”
