supporting information; experimental part, p. 2359 - 2364 (2011/02/21)
Metal-containing Janus particles are used as interfacial catalyst/emulsifiers that catalyze reactions in biphasic systems with controlled "phase selectivity", that is, conversion of the desired reaction on one side of the emulsion. The reaction may affect

Cerium(III) triflate deprotects p-methoxybenzyl ethers of simple alcohols better than the cerium(III) chloride/sodium iodide system. It can be used in 1% M instead of equimolecular amounts, giving better yields. Aromatic alcohols rearrange, but the addition of a scavenger overcomes this drawback. Unfortunately, unsaturated alcohols are deprotected with decomposition, probably due to side electrophilic additions to double bonds. A comparison between the mechanisms of cerium triflate and cerium chloride is reported. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
