Du, Yingying published the artcileHighly efficient heterogeneous copper-catalysed O-arylation of phenols by nitroarenes leading to diaryl ethers, SDS of cas: 61343-99-5, the main research area is diaryl ether green preparation; phenol nitroarene arylation copper catalyst.
The heterogeneous O-arylation of phenols by nitroarenes was achieved in DMF at 100° by using an MCM-41-immobilized bidentate nitrogen copper(II) complex [MCM-41-2N-Cu(OAc)2] as catalyst, yielding a variety of unsym. diaryl ethers I (R1 = 4-OH, 2-OH, 4-NC, etc.; R2 = H, 4-Me, 4-MeO, etc.) in good to excellent yields. This heterogeneous copper catalyst can be easily prepared by a simple procedure from com. readily available and inexpensive reagents, recovered by filtration of the reaction solution and recycled at least seven times without significant loss of activity.
Journal of Chemical Research published new progress about Aromatic ethers Role: SPN (Synthetic Preparation), PREP (Preparation). 61343-99-5 belongs to class chlorides-buliding-blocks, name is 4-(4-Chlorophenoxy)benzaldehyde, and the molecular formula is C13H9ClO2, SDS of cas: 61343-99-5.
