Technology Process of α-P4S3I2

There total 2 articles about α-P4S3I2 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:

phosphorus + iodine (7553-56-2,12190-71-5,8031-47-8) + sulfur (7704-34-9) → diphosphorus tetraiodide (13455-00-0) + phosphorous triiodide (13455-01-1) + α-P4S3I2 (19257-89-7,92356-56-4)

Guidance literature:

In carbon disulfide; formation as by product by prepn. of PI3 and P2I4 from P and I in CS2 poluted with S;;

DOI:10.1021/ja01401a001

Reference yield:

phosphorous (12185-10-3) → diphosphorus tetraiodide (13455-00-0) + phosphorus sulfide (12037-82-0) + phosphorous + phosphorous triiodide (13455-01-1) + α-P4S3I2 (19257-89-7,92356-56-4)

Guidance literature:
