Reference of 2142-70-3, A common heterocyclic compound, 2142-70-3, name is 1-(2-Iodophenyl)ethanone, molecular formula is C8H7IO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
A mixture of 1 -(2-iodophenyl) ethan-l-one (l.Og, 4.06 mmol), sodium methanesulfunate (0.83g, 8.12 mmol) and copper iodide (77mg, 0.4 mmol) in 10 mL of DMSO was heated to 100 C under argon. The cooled mixture was partitioned by EA and water. The organic layer was separated, and the aqueous layer was extracted with EA twice. The combined organic layers were washed with brine, dried over MgS04, and concentrated in vacuo to afford the product, l-(2-(methylsulfonyl)phenyl) ethan-l- one, which is yellow solid with a yield of 0.77g (95%).
The synthetic route of 2142-70-3 has been constantly updated, and we look forward to future research findings.
