Reference of 36847-10-6, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 36847-10-6, name is 4,6-Dibromopyrimidine. A new synthetic method of this compound is introduced below.
To CH2Cl2 solution (20 mL) containing pmbNOH (25 mg; 0.10 mmol) was added excess Ag2O (ca. 1 mmol) with being stirred at room temperature. The mixture was stirred for further 20 min. Filtration followed by concentration under reduced pressure gave an oily product (pmbNO). The IR spectrum supports the absence of the hydroxyl group. IR (neat, ATR) 729, 860, 985, 1191, 1223, 1246, 1344, 1365, 1444, 1481, 1555, 2935, 2984 cm-1. The MS spectrum indicates the loss of two H atoms from the precursor. MS (ESI+-TOF in MeOH) m/z 275.16 [(M+Na)+]. At this stage, pmbNO could be characterized by means of ESR spectroscopy and SQUID magnetometry (see the main text). The resultant pmbNO was dissolved again in CH2Cl2 (20 mL) and covered with a hexane solution (5 mL) of anhydrous [Cu(hfac)2] (95 mg). After slow diffusion of the solutions, reddish brown plates of [Cu3(pmbNO)2(hfac)4]¡¤(C6H14) (10 mg; 12%) were grown and separated on a filter.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,36847-10-6, 4,6-Dibromopyrimidine, and friends who are interested can also refer to it.
