General Description

1-Styrylnaphthalene is a chemical compound with the molecular formula C18H14. It is an aromatic hydrocarbon that is commonly used in the production of styrene-based polymers and resins. 1-Styrylnaphthalene is a colorless to light yellow liquid at room temperature, with a pleasant aromatic odor. It is mainly used as a precursor to the production of thermoplastic elastomers, coatings, adhesives, and other industrial products. Additionally, it is a key intermediate in the synthesis of various organic compounds and pharmaceuticals. 1-Styrylnaphthalene is also used as a fluorescent tracer in biological and environmental research due to its unique photophysical properties. However, it should be handled with care as it is flammable and may cause skin and eye irritation upon contact.

C(sp2)-C(sp2) cross coupling reactions catalyzed by an active and highly stable magnetically separable Pd-nanocatalyst in aqueous media

A new magnetite Pd-nanoparticle supported (4,5-diazafluoren-9-one)-derived palladium chloride (7) was synthesized, characterized and introduced. The nanocatalyst exhibited an efficient activity in Suzuki cross-coupling reactions with an environmentally-friendly (H2O/DMF) solvent system for 1-3 h at 100 °C and Mizoroki-Heck cross-coupling reactions. The catalyst can easily be recovered from the reaction system by using an external magnet and reused several times with high yields. This journal is

Structural Effect of Pincer Pd(II)–ONO Complexes Modified with Acylthiourea on Sizes of the In Situ Generated Pd Nanoparticles During Heck Coupling Reaction

Abstract: The Pd nanoparticles generated in situ from Pd–pincer complexes catalyzed Heck coupling reaction. For this purpose, new Pd(II)–ONO pincer complexes (1–4) containing acylthiourea ancillary ligand were obtained by treating [Pd(ONO)(CH3CN)] with the respective N-substituted carbamothioyl benzamide ligand (L1–L4). Formation of these complexes was confirmed by UV–Visible, FT-IR, NMR and mass spectroscopic techniques. The sizes of in situ formed Pd nanoparticles were greatly affected by the substituent in ancillary ligand, which in turn influenced their catalytic activity towards Heck coupling reaction. The in situ formed Pd nanoparticles during Heck reaction were removed from the reaction medium and analyzed using HR-TEM to estimate the sizes of the Pd nanoparticles. Complex [Pd(ONO)((N-benzylcarbamothioyl)benzamide)] (1) which does not possess any substituent on the benzyl moiety of acylthiourea produced the smallest Pd nanoparticles with the average particle size of 3.7?nm. Hence, complex 1 showed the utmost catalytic activity. With complex 1, 51–99% of conversion was observed during Heck coupling reaction of styrene with various aryl halides. XPS results confirmed that the recovered black particles were Pd(0). A reasonable recyclability results were achieved by these in situ generated Pd nanoparticles.

A new Pd(II)-supported catalyst on magnetic SBA-15 for C-C bond formation via the Heck and Hiyama cross-coupling reactions

Magnetic mesoporous silica composite (MNP@SiO2-SBA) was obtained via embedding magnetite nanoparticles between SBA-15 channels. It was silylated with N-(3-(trimethoxysilyl)propyl)picolinamide (TMS-PCA) and then complexed with Pd(II). The obtained supported Pd(II) catalyst (MNP@SiO2-SBA-PCA) was characterized by conventional methods. The prepared magnetic catalyst showed high activity in the Heck and Hiyama reactions under optimal reaction conditions, including solvent, amount of catalyst, base, and temperature. Aryl bromides and iodides showed better results than aryl chlorides, and the catalyst exhibited noticeable stability and reused several times.
