A cobalt-catalyzed decarboxylative methylation of aliphatic redox-active esters [ N-(acyloxy)phthalimides; RAEs] with trimethylaluminum under mild conditions was developed, providing a method for transforming a carboxylate group into a methyl group without redox fluctuation. Primary and secondary RAEs were both amenable substrates, whereas a tertiary RAE delivered an elimination product. Triethylaluminum was also used to deliver a decarboxylative ethylation product.

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.
