Synthesis, structure and catalysis of a NHC-Pd(II) complex based on a tetradentate mixed ligand

Bis-benzimidazolium salt (S)-2,2′-bis[2′′-(N-picolyl-benzimidazoliumyl)ethoxy]-1,1′-binaphthyl hexafluorophosphate [(S)-LH2]·(PF6)2 and its NHC palladium(ii) complex [(S)-LPd](PF6)2 (1) have been prepared and characterized. Complex 1 is formed by one tetradentate mixed ligand (S)-L and one Pd(ii) ion, in which one 15-membered ring and two 6-membered rings are present. In this complex, intramolecular π-π interactions between naphthalene rings and benzimidazole rings are observed. Additionally, the catalytic activity of complex 1 in three types of C-C coupling reactions (Suzuki-Miyaura, Heck-Mizoroki and Sonogashira reactions) was investigated. The results show that complex 1 is an effective catalyst in these coupling reactions.

Substituent effect on the photochemical and photophysical properties of 4,4′-distyrylbiphenyl derivatives

Photochemical properties of 4,4′-distyrylbiphenyl (DSBP) derivatives have been studied. While the introduction of methoxy groups at meta-positions does not influence the photoisomerization of DSBP, the introduction of methyl substituents at the biphenyl moiety (MDSBP) changed the photoisomerization from one-way cis-to-trans photoisomerization for DSBP to cistrans mutual photoisomerization for MDSBP.

Wittig Reactions of Phosphoniomethylaryl Compounds with Sulfonated Aromatic and Heteroaromatic Aldehydes

Bis(triphenylphosphoniomethyl)aryl dichloride derivatives react with aromatic or heteroaromatic aldehydes which have a sulfonic or carboxylic group attached to the ring system, to yield stilbene compounds of a betaine-type structure.These betaines are reacted further with various aromatic or heteroaromatic aldehydes yielding asymmetrically substituted derivatives in excellent yields.This new method is widely applicable to the preparation of water-soluble, fluorescent whitening agents of the bis-stilbene type.
