Abstract

Chemistry Chemistry, Physical Physical Sciences Science & Technology
2-Methylpropene in the presence of W-H/Ni-1%-Al2O3-(500) is transformed in high selectivity into a mixture of 2,3-dimethyl-butenes (2,3-DMBs = DMB-1 and DMB-2) and neohexene. 2,3-DMBs arise from the unfavoured 2-methylpropene self-metathesis reaction whereas the neohexene originates from a cascade reaction: 2-methylpropene dimerisation followed by cross metathesis.
