The first protocol for boron-promoted ether interchange reaction of methoxynitroarenes was described. A series of methoxynitroarenes and alcohols, including primary, secondary, as well as tertiary alcohols were reacted smoothly in moderate to good yields under the optimized reaction conditions. This protocol constitutes an operationally simple and scalable strategy for the synthesis of alkyl nitroaromatic ethers. Moreover, the new reactivity of boron reagents was discovered.

A heterogeneous C-O coupling reaction between aryl iodides and aliphatic alcohols was achieved in neat alcohol or toluene at 110 °C in the presence of 10 mol% of the MCM-41-immobilized 1,10-phenanthroline-copper(i) complex [MCM-41-1,10-phen-CuI] with Cs2CO3 as a base, yielding a variety of aryl alkyl ethers in good to excellent yields. The new heterogeneous copper catalyst can easily be prepared by a simple procedure from commercially available and inexpensive reagents, and recovered by filtration of the reaction solution and recycled at least 8 times without significant loss of activity.
Decarboxylative etherification of aromatic carboxylic acids
Bhadra, Sukalyan,Dzik, Wojciech I.,Goossen, Lukas J.
, p. 9938 - 9941 (2012/08/08)
Decarboxylative Chan-Evans-Lam-type couplings are presented as a new strategy for the regiospecific construction of diaryl and alkyl aryl ethers starting from easily available aromatic carboxylic acids. They allow converting various aromatic carboxylate salts into the corresponding aryl ethers by reaction with alkyl orthosilicates or aryl borates, under aerobic conditions in the presence of silver carbonate as the decarboxylation catalyst and copper acetate as the cross-coupling catalyst.
