Reaction Conditions:

with oxygen in water at 80; under 2250.23 Torr; for 1 h;

Steps:

Example 1: Synthesis of sulfur-sulfur bond-containing disulfide compounds in an oxygen atmosphere.

In a 100 mL reaction vessel, 6 g of p-methylthiophenol,48 mg (0.8 wt%)Tetracarboxylic iron phthalocyanine tetrasodium[FePc (COONa) 4] and60 mL of water; heated with stirring heated to 40 ° C, purged with oxygen,Keep the pressure inside the reactor 0.15 MPa, the reaction was stopped after 15 hours,Cooled, filtered, washed with 10 mL of water filter cake, dried to give a white solid 5.88 g,The product by NMR (see photo),MS and other methods to determine the structure ofP-Tolyl disulfide, the yield was 98%The purity of the product by HPLC was 99.5%.
