Abstract:

1-Thiohydroxypyrene(1) and its two intermediates, 1-pyrenyl-O-thiocarbamate(2) and 1-pyrenyl-S-thio- carbamate(3), were synthesized using 1-hydroxypyrene as the starting material. The key synthetic step is Newman-Kwart rearrangement. The results indicate that the Newman-Kwart rearrangement is more effective in suitable solvent than conventional method based on pure organic compound. The structures of compounds 13 were characterized by FTIR, NMR, GC-MS and elementary analysis. The crystal structures of two new compounds(2 and 3) were determined by single crystal X-ray diffraction analysis. The whole synthetic process is simple, mild and with high yield.

Key words: Newman-Kwart rearrangement, 1-Thiohydroxypyrene, Crystal structure
