We find that Lewis acid catalysts hydrogenate the furfural to furfuryl alcohol, which is then etherified with 2\u2010propanol. The catalytic activity is correlated with an empirical scale of Lewis acid strength and exhibits a volcano behavior. Lanthanides are the most active, with DyCl<jats:sub>3<\/jats:sub> giving complete furfural conversion and a 97\u2009% yield of furfuryl alcohol at 180\u2009\u00b0C after 3\u2005h. The combination of Lewis acid and Ru\/C catalysts results in synergy for the stronger Lewis acid catalysts, with a significant increase in the furfural conversion and methyl furan yield. Optimum results are obtained by using Ru\/C combined with VCl<jats:sub>3<\/jats:sub>, AlCl<jats:sub>3<\/jats:sub>, SnCl<jats:sub>4<\/jats:sub>, YbCl<jats:sub>3<\/jats:sub>, and RuCl<jats:sub>3<\/jats:sub>. Our results indicate that the combination of Lewis acid\/metal catalysts is a general strategy for performing tandem reactions in the upgrade of furans.<\/jats:p>","DOI":"10.1002\/cssc.201500212","type":"journal-article","created":{"date-parts":[[2015,5,26]],"date-time":"2015-05-26T19:12:52Z","timestamp":1432667572000},"page":"2046-2054","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":104,"title":["Liquid\u2010Phase
