Here, an innovative approach to produce renewable pentadiene is described: converting levulinic acids to 1,4-pentanediol, followed by dehydration to pentadiene affording 77.5% yield over a multifunctional Ce/ZrSi catalyst. Impressively, a synergistic effect between Ce and ZrSi was disclosed for the direct dehydration, and further transformation was relatively stimulated from the undesirable product 2-methyltetrahydrofuran toward pentadiene. Moreover, the direct dehydration took priority over the pentadiene synthesis among the two reaction pathways.
