Structures and Fluorescent Properties of Cadmium(II) Complexes with 1D and 2D Structures Based on Tridentate Benzimidazole Ligands

The cadmium(II) complexes [CdL1(m-nba)2] (1), [CdL1(p-nba)2]¡¤C2H5OH (2), [CdL2(p-nba)2]¡¤CH3OH (3), and [CdL2(p-nbat)2] (4) containing the ligands L1 and L2 [L1 = 2,6-bis(benzimidazol-2-yl)pyridine, L2 = bis(2-benzimidazolylmethyl)amine] were synthesized and characterized (m-nba, p-nba, and p-nbat are the anions of p-nitrobenzoic acid, m-nitrobenzoic acid, and p-nitrobenzeneacetic acid, respectively). The complexes were investigated by X-ray single crystal diffraction, elemental analysis as well as IR and fluorescence spectroscopy. Compounds 1-3 contain a distorted pentagonal bipyramidal coordination sphere with CdII coordinated by two carboxylate ligands in bidentate-chelating mode, whereas complex 4 exhibits a distorted octahedral arrangement with one carboxylate ligand in bidentate-chelating and the other in monodentate coordination mode. 1 and 2 form a 1D chain interplayed by hydrogen bonding and strong pi-pi stacking interactions. 3 and 4 vary from 1D chain into 2D single-layer and double-layer networks because of more extensive hydrogen bonding interactions. The complexes show emission maxima in the blue region in the solid state and emission bands are red-shifted compared to those of the free ligands.

Palladium-catalyzed enantioselective Heck alkenylation of trisubstituted allylic alkenols: a redox-relay strategy to construct vicinal stereocenters

An enantioselective, redox-relay Heck alkenylation of trisubstituted allylic alkenol substrates has been developed. This process enables the construction of vicinal stereocenters in high diastereo- and enantioselectivity and allows the formation of enolizable alpha-carbonyl methyl-substituted stereocenters with no observed epimerization under the reported reaction conditions.

The palladium-mediated C?C bond formation that uses alpha-bromomethylbutenolide and boron derivatives as coupling partners accounts for the key step of this synthetic approach. Our strategy exclusively affords the endocyclic adduct and represents an alternative to Heck-type reactions. The synthesis and characterization of two nostoclide analogues has also been reported.

Sequential silylcarbocyclization/silicon-based cross-coupling reactions

A sequential rhodium-catalyzed silylcarbocyclization of enynes parlayed with a palladium-catalyzed, silicon-based cross-coupling reaction has been developed for the synthesis of highly substituted cyclopentanes. 1,6-Enynes reacted with benzyldimethylsilane in the presence of rhodium catalysts to afford five-membered rings bearing a (Z)-alkylidenylbenzylsilyl group. A variety of substitution patterns and heteroatom substituents were compatible. The silylcarbocyclization in which an unsaturated ester participated was also achieved. The resulting alkylidenylsilanes underwent palladium-catalyzed cross-coupling using tetra-n-butylammonium fluoride. This cross-coupling reaction displayed a broad substrate scope. A wide variety of substitution patterns, electronic properties, and heteroatoms were compatible. All of the cross-coupling reactions proceeded in high yields under very mild conditions and with complete retention of double bond configuration, resulting in densely functionalized 3-(Z)-benzylidenecyclopentanes and heterocycles.

Synthesis, characterization, self-assembly, gelation, morphology and computational studies of alkynylgold(III) complexes of 2,6-bis(benzimidazol-2′- yl)pyridine derivatives

A novel class of alkynylgold(III) complexes of the dianionic ligands derived from 2,6-bis(benzimidazol-2′-yl)pyridine (H2bzimpy) derivatives has been synthesized and characterized. The structure of one of the complexes has also been determined by X-ray crystallography. Electronic absorption studies showed low-energy absorption bands at 378-466 nm, which are tentatively assigned as metal-perturbed pi-pi* intraligand transitions of the bzimpy2- ligands. A computational study has been performed to provide further insights into the nature of the electronic transitions for this class of complexes. One of the complexes has been found to show gelation properties, driven by pi-pi and hydrophobic-hydrophobic interactions. This complex exhibited concentration- and temperature-dependent 1H NMR spectra. The morphology of the gel has been characterized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

The reaction of long chain alkenes with CO and aniline in the presence of palladium complexes of 1,2-bis-(ditertbutylphosphinomethyl)benzene produces amides with high linear selectivity, with much higher rates and catalyst stability when 2-naphthol and sodium or potassium iodide are added. Unsaturated esters including methyl 10-undecenoate from castor oil give alpha,omega- ester amides, whilst reactions in THF give N-phenylpyrrolidine.
