Abstract

Copper(II) Bromide as an Efficient Catalyst for Acetal to Bisarylmethyl Ether Interconversion. -The simple method permits the conversion of 1,3-dioxolanes and 1,3-dioxanes into bis(methoxyphenyl)methyl ethers. Mono-ethers are obtained as main products. Excellent selectivity is observed for the substrate (Vb). -(MEZAACHE, R.; HARKAT, H.; OBSZYNSKI, J.; BENKOUIDER, A.; BLANC, A.; WEIBEL*, J.-M.; PALE, P.; Tetrahedron Lett. 55 (2014) 52, 7167-7171, http://dx.
