Investigation of the reaction: of sulfur with organic compounds
- 28 Downloads
A new simple method of synthesizing 2-phenylthianaphthene and its hitherto unknown 4′, 6-dihalogeno derivatives is worked out. It is based: on the reaction of sulfur with benzyl bromide, or p-halogenobenzyl bromides. All the compounds of this type, synthesized are converted to their sulfones. When benzylidene bromide and o-chlorpbenzyl bromide are heated with sulfur, they give thianaphtheno-[3, 2-b] thianaphthene. Reaction of sulfur with p-chlorobenzyl bromide at 210–230° C, and with the analogous m-chloro-derivative at 190–210°C, gives the corresponding dichlorostilbenzenes. Action of sulfur on p- and o-methylbenzyl bromide (but not on the m-isomer) converts them to the corresponding dimethylstilbenes.
