A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic diamides serve as the powerful ligands. The tert-butoxide is first demonstrated as a ligand for Cu-catalyzed coupling reaction, leading to alkoxylation of aryl iodides complete at room temperature. Additionally, a number of carbohydrate derivatives are applicable for this coupling reaction, affording the corresponding carbohydrate-aryl ethers in 29-98% yields.

Several new methylenedioxyphenyl (MDP) ethers were synthesised from sesamol and methoxy substituted sesamols and screened as pyrethrum synergists.In general, the synergistic activity increased with the methoxyl substituents and decreased in the corresponding alkenyl analogs.The synergistic activity of alkyl ethers was found to vary with the alkyl chain, n-propyl ethers showing the maximum.In the case of alkenyl ethers, the activity followed the order γ,γ-dimethyl allyl > β-methallyl > allyl and showed no correlation between Rm and synergistic activity.
