In this work, two types of novel photoinitiaors containing phototrigger were prepared to overcome oxygen inhibition in the UV- curing system in the absence of hydrogen donor. The structures of prepared novel photoinitiators were determined by nuclear magnetic resonance (NMR) and high resolution MS (HR[sbnd]MS) spectra data. The photo chemical behavior and photo-reactivity were also evaluated by ultraviolet-visible (UV–vis) spectroscopy and real-time Fourier transform infrared spectroscopy (RT-FTIR), respectively. The results show the prepared photoinitiators exhibit remarkable redshift compared to the commercial BP (benzophenone) and Irgacure 907 (2-methyl-1-(4-methylsulfanylphenyl)-2-morpholin-4-ylpropan-1-one), fast photolysis by C[sbnd]S bond, good photo initiation and significant overcoming oxygen inhibition for some compounds, which can be used as one-component photoinitiator candidates.

Modern pentafluorosulfanyl (SF5) chemistry has an Achilles heel: synthetic accessibility. Herein, we present the first approach to aryl-SF4Cl compounds (key intermediates in state-of-the-art aryl-SF5 synthesis) that overco

One-Pot Two-Step Synthesis of Aryl Sulfur Compounds by Photoinduced Reactions of Thiourea Anion with Aryl Halides

(Equation presented) The photoinduced reactions of aryl halides with the thiourea anion afford arene thiolate ions in DMSO. These species without isolation, and by a subsequent aliphatic nucleophilic substitution, S RN1 reaction, oxidation, or protonation, yield aryl methyl sulfides, diaryl sulfides, diaryl disulfides, and aryl thiols with good yields (50-80%). This is a simple and convenient approach which involves the use of the commercially available and inexpensive thiourea in a one-pot two-step process for the synthesis of aromatic sulfur compounds.
