General procedure: Representative procedure for 17: A Schlenk tube was charged with 2 (400mg, 2.03mmol), dry THF (10mL), anhydrous cobalt(II) chloride and a stirring bar. In a separate Schlenk tube, a solution of lithium diisopropylamide (LDA) was prepared in THF (25mL) from diisopropylamine (700muL, 5.0 mmol) and n-butyl lithium (3.15mL of a 1.6M solution in hexane, 5.0 mmol). The LDA-solution was added under protection from air to the solution of 2 and CoCl2. After the mixture has been stirred overnight, all volatile materials were removed on a vacuum line. The Schlenk vessel was transferred into the glove-box and the dark colored solid residue was dissolved in a small volume of dry dichloromethane. Layering the solution with dry n-hexane afforded brown single crystals of the product.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.13395-16-9,Bis(acetylacetone)copper,as a common compound, the synthetic route is as follows.

General procedure: In a typical synthesis of Cu40Ag60, 0.45mmol Cu(acac)2 and 0.35 Ag (ac) was mixed with 3mL of OAm, 1 mL of OAc and 11mL of ODE. All synthesis was conducted in a four-necked glass reactor allowing the precise temperature control and inert gas atmosphere under dark conditions. Firstly, the mixture was heated to 60C and kept at this temperature for 10min. Then, the mixture was heated to 180C and kept at this temperature for 30min before it was cooled down to room temperature. After cooling, the resultant reaction mixture was collected with hexane (2mL) and the NPs were separated by centrifugation (8500rpm, 12min) after adding isopropanol (40mL). To further purify the yielded CuAg NPs, the product was centrifuged (8500rpm, 12min) one more time with ethanol (40mL). Finally, the remaining product was dispersed in hexane (10mL) for further use. By using the same recipe and varying metal precursor amounts, two different compositions of CuAg NPs were synthesized. Reductive mixing of 0.3mmol Cu(acac)2 and 0.5 Ag(ac) resulted in Cu30Ag70 NPs and mixing 0.6mmol Cu(acac)2 with 0.4 Ag (ac) led to Cu60Ag40. Synthesis of Ag NPs was conducted with the same recipe without using Cu precursor.
