There total 10 articles about tetrakis(phenylethynyl)stannane 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: 83.0%

tin(IV) chloride (7646-78-8) + phenylacetylene (536-74-3) → tetrakis(phenylethynyl)tin (21890-32-4)

Guidance literature:

DOI:10.1039/c6nj03905g

Reference yield: 77.0%

tin tetra(N,N-diethylcarbamate) + phenylacetylene (536-74-3) → carbon dioxide (124-38-9,18923-20-1) + tetrakis(phenylethynyl)tin (21890-32-4) + diethylamine (109-89-7)

Guidance literature:

With zinc(II) chloride; In toluene; at 110 ℃; for 1.5h; Solvent; Temperature; Reagent/catalyst; Time;

DOI:10.1007/s11172-014-0508-8

Reference yield: 65.0%

lithium phenylacetylide (4440-01-1) + tin(IV) chloride (7646-78-8) → tetrakis(phenylethynyl)tin (21890-32-4)

Guidance literature:

In toluene; 25 mmol SnCl4 (25 mmol) in toluene were added dropwise to a suspension of 100 mmol LiCCC6H5 in toluene within a period of 30 min at -78°C; after warming to room temp., the mixt. was refluxed for 3 h;; the mixt. was extracted with hexane/toluene 1:2 in a Soxhlet apparatus, and concd. in vac.;;
