https://www.selleckchem.com/products/Cyt387.html An efficient domino process is developed for the synthesis of diversely substituted 2,3-dihydrobenzo[b]thiophenes from 2-iodoketones using a Cu-catalyst and easily available xanthate as a sulfur surrogate in good yields. This domino method has been expanded for the synthesis of 2-acylbenzo[b]thiophenes using in situ generated iodine (I2) from by-product KI in high yields. Treatment of xanthate with the copper(ii)-catalyst reduced it to a Cu(i)-catalyst, which initiates the catalytic cycle. A possible mechanism has been proposed based on the results from XPS-analysis, an iodine color test and several other control experiments.We have investigated the self-assembly of a strong dipolar molecule (LDipCC) on the semiconducting Si(111)-B surface with scanning tunneling microscopy (STM), density functional theory (DFT) calculations and STM simulations. Although the formation of an extended two-dimensional network was clearly revealed by STM under ultra-high vacuum, the assignment of a specific STM signature to the different terminal groups from the LDipCC molecular unit required a complete analysis by numerical simulations. The overall observed assembly is explained in terms of STM contrasts associated with the molecular structure of LDipCC and the molecule-surface interactions. To distinguish the relative arrangement of the dipolar molecules within the assembly, a rational combination of experimental results and electronic structure calculations allows us to identify a single adsorbed LDipCC phase in which the molecular dipoles are homogeneously arranged into a parallel fashion on the Si(111)-B surface.Electrochemical sensors are used by millions of patients and health care providers every year, yet these measurements are hindered by compounds that also exhibit inherent redox activity. Acetaminophen (APAP) is one such interferent that falls into this extensive class. In this work, an osmium-based redox polymer was used for
