Technology Process of bromo(nitrilo)-lambda~4~-sulfane

There total 3 articles about bromo(nitrilo)-lambda~4~-sulfane which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

(S4N3)(1+)*Br(1-)=(S4N3)Br (857244-85-0) → thiazyl bromide (52509-85-0)

Guidance literature:

In neat (no solvent); carefully warming of S4N3Br in a flow cell; passing of the evolved gases throuh the cell, IR spectroscopy;

DOI:10.1016/0368-2048(89)80025-8

Reference yield:

bromine (7726-95-6) + tetrasulfur tetranitride (28950-34-7) → thiazyl bromide (52509-85-0)

Guidance literature:

In carbon disulfide; addn. of excess Br2 to a soln. of S4N4 in CS2; storage for 24 h;; pptn.; fast drying on clay;;

Reference yield:

thiazyl chloride (17178-58-4) + potassium bromide (7558-02-3,7758-02-3) → thiazyl bromide (52509-85-0)

Guidance literature:

In neat (no solvent); passing of thiazyl bromide over heated (900-950 K) KBr; IR spectroscopy;
