Fluorescent and luminescent reporters that signal molecular events of interest by modulating the ratio of peaks in their emission profile have advantages over reporters that simply modulate their emission intensity, since ratiometric measurement is concentration-independent and allows them to be effective in complex contexts, such as living cells or sensor microarrays. We herein describe a general platform for the design of ratiometric probes based on a heterometallic Tb3+/Eu3+ bis-lanthanide ensemble, consisting of a mixture, or “cocktail”, of otherwise identical heterometalated chelates. The chelate contains an organic photon antenna that sensitizes the Tb3+/Eu3+ luminescence. The contributions of the two metals to the composite luminescence spectrum can be tuned to the same relative scale by adjusting the stoichiometry of the cocktail, allowing subtle changes in their ratio to be accurately measured. Importantly, the ratio responds to chemical and environmental changes experienced by the photon antenna, making the system an ideal platform for the design of chemical and enzymatic probes. As proofs of concept, we describe a ratiometric probe for esterase activity and a polarity-responsive ratiometric sensor.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, HPLC of Formula: C46H62NO3PPdS, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 1445085-55-1, Name is Methanesulfonato(2-dicyclohexylphosphino-2′,4′,6′-tri-i-propyl-1,1′-biphenyl)(2′-amino-1,1′-biphenyl-2-yl)palladium(II), molecular formula is C46H62NO3PPdS

A stereoselective bromocyclopropanation of allylic alcohols using dibromomethylzinc bromide is described. Spectroscopic studies to monitor the formation of transient intermediates not only led to the development of a more-atom-economical halocyclopropanation reaction, but also highlighted the unique role of ether additives in the process. The desired bromo-substituted cyclopropanes were isolated in high yields and excellent diastereo- as well as enantioselectivities using readily available reagents.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

We synthesized a recyclable palladium ionic catalyst, Ti0.97Pd0.03O1.97, using a solution combustion method (SCM), and characterized by XRD and Rietveld refinement. The synthesized Pd ionic catalyst is stable, insensitive to moisture and air, and easy to handle. The new catalyst has exhibited a phenomenal result for the Suzuki-Miyaura cross-coupling reaction with a broad substrate scope, and the reaction proceeds in an aqueous medium. The new catalyst proved beneficial and produced excellent yields irrespective of aryl halide used in the reaction (electron-rich or electron-poor or heterocyclic compounds) and shown a turnover frequency (TOF) of 14?25 h?1 for different reactions. The catalyst was coated on a cordierite monolith (Mg2Al4Si5O18), which enhanced the applicability of the catalyst, and made the handling and recycling of the catalyst very easy. Suzuki Miyaura reaction was carried out using both Pd-powder catalysts as well as the Pd-coated honeycomb, which gave almost similar results. We have demonstrated the recyclability of Pd coated cordierite monolith and shown the superiority of the catalyst over the other Pd catalysts for the Suzuki-Miyaura reaction.

The electrochemistry of 1,1?-bis(dicyclohexylylphosphino)ferrocene (dcpf) was examined in methylene chloride with tetrabutylammonium hexafluorophosphate or tetrabutylammonium tetrakis(pentafluorophenyl)borate as the supporting electrolyte. The oxidation of dcpf is complicated by a follow-up reaction. Seven new complexes containing dcpf and one new compound containing 1,1?-bis(di-tert-butylphosphino)ferrocene (dtbpf) were prepared and characterized. The new complexes were analyzed by cyclic voltammetry and the oxidation of these complexes occurred at a more positive potential than the free ligand. In addition, the X-ray structure of [PdCl2(dcpf)] was determined and compared to other palladium complexes containing bisphosphinometallocene ligands. Five different palladium complexes containing bisphosphinometallocene ligands were examined as catalyst precursors in Buchwald-Hartwig catalysis.

Reaction of bromonaphthofurans with bis(pinacolato)diboron

The synthesis of a dimeric pyranonaphthoquinone (8) was investigated focusing on a late-stage biaryl coupling of suitably functionalized bromonaphthofurans by using Suzuki-Miyaura methodology. Bromonaphthofuran (16) underwent reaction with bis(pinacolato)diboron in the presence of PdCl2(dppf) to afford boronate ester (21) and furonaphthofuran (22). ‘In situ’ coupling of the boronate ester (21) with aryl bromide (16) to the desired dimer (11) was not realized. Bromonaphthofuran (17), prepared by Diels-Alder/retro-Claisen reaction of bromonaphthoquinone (24) with diene (25), underwent Suzuki-Miyaura coupling to naphthofuran (27) and boronate ester (28). Numerous attempts to alter the reaction conditions to effect homocoupling of bromide (17) to biaryl (19) were unsuccessful. Bromopyranonaphthoquinone (18) prepared by oxidative rearrangement of (17) failed to undergo Suzuki-Miyaura coupling.
