612-55-5, A common compound: 612-55-5, name is 2-Iodonaphthalene, belongs to iodides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
General procedure: To a Schlenk tube were added aryl iodides 1 (0.2 mmol, 1.0 equiv),1,2-diphenylethynes 2 (0.2 mmol, 1.0 equiv), 2-bromobenzoic acid 3 (0.24 mmol, 1.2equiv), PdCl2(dppf) (0.01 mmol, 5 mol %), K2CO3 (0.6 mmol, 3.0 equiv), Me4NOAc(0.6 mmol, 3.0 equiv), and DMSO (0.2 M, 1 mL). Then the tube was charged with nitrogen, and was stirred at 140 oC (oil bath temperature) for the indicated time until complete consumption of starting material as monitored by TLC analysis. After the reaction was finished, the resulting suspension was filtered and washed with ethyl acetate. The combined filtrates were concentrated under reduced pressure and purifiedon a silica-gel column chromatography (petroleum ether/EtOAc) to give product 4.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Iodonaphthalene, other downstream synthetic routes, hurry up and to see.
