A green and efficient visible-light promoted oxidative desulfurization protocol has been proposed for the construction of unsym. ureas R1NHC(O)N(R2)R3 [R1 = Ph, propan-2-yl, 4-chlorophenyl, etc.; R2 = H, Et, n-Pr, n-Bu, Bn, cyclohexyl; R3 = n-Bu, Bn, 2-(thiophen-2-yl)ethyl, etc.; R2R3 = -(CH2)5-, -(CH2)2O(CH2)2-] and I under mild conditions with broad substrate scope and good functional group tolerance. Most appealingly, the reaction can proceed smoothly without adding any strong oxidants. Control experiments and computational studies support a mechanism involving water-assisted in situ generation of thioureas and photocatalytic oxidative desulfurization. The present method provides a promising synthesis strategy for the formation of diverse and useful unsym. urea derivatives I in the fields of pharmaceutical and synthetic chem. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Related Products of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Related Products of 2253-73-8
