Adding a certain compound to certain chemical reactions, such as: 14862-52-3, name is 3,5-Dibromochlorobenzene, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 14862-52-3, Formula: C6H3Br2Cl

General procedure: Typically, TDPP (200 mg, 0.27 mmol), dibromobenzene derivatives 0.11 mmol, anhydrous Cs2CO3(200 mg, 0.61 mmol), PivOH (7.9 mg, 0.08 mmol), Pd2(dba)3 (4.00 mg, 1.5 mol%), tris(o-methoxyphenyl)phosphine (3.08 mg, 3 mol%) were successively added into a Schlenk tube. The tube was purged by three repetitions of vacuum and argon filling. Then, 5 mL anhydrous toluene was added via syringe.The reaction solution was deoxygenated using three freeze-vacuum-thaw cycles, and then rigorouslystirred at 100 C for 24 h under argon atmosphere. Removal of the toluene by rotary evaporatoraorded the crude product, which was then purified by chromatogragh column (CC) on silica gelusing a mixture of CH2Cl2 and hexane as eluent, giving the target molecules Ms1~9.

Application of 2687-12-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2687-12-9, name is Cinnamyl chloride belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.

General procedure: Briefly, a mixture of alkylimidazoles such as 1-methyl-1H-imidazole (MIM), 1-hexyl-1H-imidazole(HIM), 1-octyl-1H-imidazole (OIM), and 1-decyl-1H-imidazole (DIM) (1 mmol), as well as cinnamylchloride (1 mmol) solvent-free were microwaved to 200 MW at 80 C for 5 min (optimumreaction condition). Reaction completion was marked by separation of dense IL. Products suchas 1-methyl-3-cinnamylimidazolium chloride [CMIM]Cl, 1-hexyl-3-cinnamylimidazolium chloride[CHIM]Cl, 1-octyl-3-cinnamylimidazolium chloride [COIM]Cl, and 1-decyl-3-cinnamylimidazolium chloride [CDIM]Cl were isolated by decanting toluene to remove any unreacted starting materialsand solvents. Subsequently, ILs were rinsed with diethyl ether (4 10 mL) separating afterward thislatter layer by decantation. In each case, ILs were finally dried under reduced pressure to get rid of thevolatile organic compounds.

The synthetic route of Cinnamyl chloride has been constantly updated, and we look forward to future research findings.
