Engineering of molecular stacking arrangement via environmental stimuli is of particular interest in stimuli-responsive self-assembling architectures. A novel dual photo-functionalized diacetylene ((Z)-CNBE-DA) molecule was synthesized, in which photo-res

Novel tetra-methoxy resorcinarene tetra-hydrazide (TMRTH) has been synthesized and used as a reducing agent and a capping agent for the synthesis of water-dispersible stable palladium nanoparticles (PdNPs). The TMRTH-PdNPs were characterized by UV-Vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, and powder X-ray diffraction. The synthesized nanoparticles are polydispersible with a size of 5 ± 2 nm and were found to be recyclable over five cycles maintaining a catalytic activity in the Suzuki-Miyuara cross-coupling reaction. The nanocatalyst was superior in catalytic performance to conventional palladium catalysts with respect to reaction time, catalyst loading and recyclability. TMRTH-PdNPs show promise for their use in biological applications as they exhibit good antibacterial activity against gram-positive bacteria.

An efficient catalytic system for Suzuki-Miyaura coupling reactions in neat water has been developed by using a water-soluble Pd(l-proline)2 catalyst. Under the optimized conditions, various biaryl compounds were obtained in good to excellent yields and a wide range of functional groups on the tested substrates were well tolerated. The catalytic system could be reused at least six times with no significant loss in its activity.

(Equation Presented) Room-temperature ionic liquids promote various transition metal-catalyzed reactions in the solution phase. Here, for the first time, we show that these effects are translatable to solid-phase reactions. The Suzuki-Miyaura cross-coupli

Here we show that a structure containing a polymeric interlocking daisy chain is obtained from the reaction of an inorganic-organic [2]rotaxane [HB{CrIII7NiII(μ-F)8(O2CtBu)16}], where B is an organic thread terminated with a bi-pyridyl unit, with an oxo-centered metal carboxylate triangle [FeIII2CoII(μ3-O)(O2CtBu)6(HO2CtBu)3].

A one-pot protocol for the fluorosulfation and Suzuki coupling of phenols is described. The tandem reaction proceeds efficiently at room temperature, and various biaryls and biaryl fluorosulfates were obtained in good to excellent yields. Furthermore, biaryl fluorosulfates were utilized as versatile building blocks for the preparation of terphenyls. The Royal Society of Chemistry 2020.
An acetatopalladium(II) complex with 1-benzyl-N-(3,5-di-tert-butylsalicylidene)piperidin-4-amine: Synthesis, structure and catalytic applications in Suzuki–Miyaura coupling of arylboronic acids with hydroxyaryl halides

The Schiff base 1-benzyl-N-(3,5-di-tert-butylsalicylidene)piperidin-4-amine (HL) and its acetatopalladium(II) complex having the formula [Pd(L)(OAc)] were synthesized. Both HL and [Pd(L)(OAc)] were characterized using elemental analysis and various spectroscopic (infrared, UV–visible, 1H NMR and 13C NMR) and mass spectrometric measurements. The molecular structure of the complex was determined using X-ray crystallographic analysis. In the complex, the pincer-like NNO-donor L? and the monodenate OAc? provide a distorted square-planar N2O2 coordination environment around the metal centre. The physicochemical properties and the spectroscopic features of [Pd(L)(OAc)] are consistent with its molecular structure. The complex was found to be an effective catalyst for the Suzuki–Miyaura cross-coupling reactions of hydroxyaryl halides with arylboronic acids in predominantly aqueous media. The reactions afforded hydroxybiaryl products in good to excellent yields with a wide substrate scope.

A N-benzyl-4-amino-2,2-dimethylbutanoic acid-based system has been developed as a new oxidatively activated safety catch linker for reaction monitoring and optimisation on solid support. The CAN promoted oxidative debenzylation of the tertiary N-benzylamine moiety, followed by concomitant cyclisation and release of alcohols and amines has been demonstrated both in solution phase model studies and on the solid phase. The linker system has been applied to the solid phase synthesis of a collection of phenol derivatives, and to the demonstration of the attachment and release of a chiral auxiliary from a solid support.
