Technology Process of Dichlorodioctyltin

There total 16 articles about Dichlorodioctyltin 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: 98.0%

trioctylaluminum (1070-00-4) → n-octyltin trichloride (3091-25-6) + di-n-octyltin dichloride (3542-36-7) + trioctyltin chloride (2587-76-0)

Guidance literature:

With tert-butyl methyl ether; tin(IV) chloride; at 50 ℃; for 0.75h; Product distribution / selectivity;

Reference yield: 95.0%

tin (7440-31-5) + n-chlorooctane (111-85-3) → di-n-octyltin dichloride (3542-36-7) + trioctyltin chloride (2587-76-0)

Guidance literature:

With catalyst: dibenzo-18-crown-6; In N,N-dimethyl-formamide; 160°C; excess KI;; analyzed by GLC;;

DOI:10.1016/0022-328X(87)80275-9

Reference yield: 54.3%

n-chlorooctane (111-85-3) + tin(IV) chloride (7646-78-8) → tetraoctyltin (3590-84-9) + di-n-octyltin dichloride (3542-36-7) + trioctyltin chloride (2587-76-0)

Guidance literature:

With sodium; In Petroleum ether; (Ar); vigorous stirred suspn. of Na was maintained at 115°C for 0.5 h, one drop of SnCl4 was added and ClC4H9 was added dropwise within 3 h at 30-40°C, after 1 h stirring SnCl4 (4:1 mol) was dropped into mixt. (same temp.) within 75 min; after stirring for a further h at 30-40°C mixt. was filtered off and residue treated with tBuOH, solvents were distd. off from filtrate; identification by GC after methylation;
