Synthetic Route of 608-28-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 608-28-6 name is 2-Iodo-1,3-dimethylbenzene, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: Under nitrogen atmosphere, Cu2O (10 mol %), DABCO (25 mol %), and a stirring bar were added into a 10 mL oven-dried sealed glass tube (as shown in Figure S1). Then NMP (0.5 mL), aryl iodides (0.125 mmol, 1.0 equiv.) and PhSiH3 (0.75 mmol, 6 equiv.) were injected by syringe. The tube was then sealed and CO2 (0.67 mmol, 5.4 equiv., 15 mL) as well as NH3 (0.67 mmol, 5.4 equiv., 15 mL) were injected by syringe after N2 was removed under vacuum. Finally, the mixture was stirred for 24 hr in a pre-heated-to-130 C alloyed block. After the reaction was finished, the tube was cooled to room temperature and the pressure was carefully released. The yield of were measured by GC analysis using dodecane as the internal standard or by flash chromatography on silica gel (petroleumether/ethyl acetate).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 2-Iodo-1,3-dimethylbenzene, and friends who are interested can also refer to it.
