4028-63-1, A common heterocyclic compound, 4028-63-1, name is 2,4,6-Trimethyliodobenzene, molecular formula is C9H11I, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: 4-Iodoanisole (1mmol), TMSA (1.1mmol) and K2CO3 (2mmol) were added to a freshly prepared solution of PdNPs (5mL) in a 25mL round bottomed flask fitted with stopper. Then, the reaction mixture was stirred at 40¡ãC. The reaction progress was monitored by TLC, until complete consumption of aryl iodide. To the reaction mixture containing in situ formed 4-ethynylanisole the next batch of aryliodide (1mmol) was added and the reaction mixture was further allowed to stir until complete consumption of the arylacetylene. In this manner the targeted unsymmetrical diarylacetylene was formed. The detailed procedure is provided in the Supp. Info. Detailed procedure for synthesis of symmetrical diarylacetylenes is also mentioned in SI.
The synthetic route of 4028-63-1 has been constantly updated, and we look forward to future research findings.
