Unusual carbon scrambling in the ethene homologation reaction. Evidence for different intermediates in the ethene homologation and metathesis reactions

Abstract

The ¹³C content in the propene formed by the homologation reaction of ¹³C₂H₄ on a reduced MoO_x–SiO₂–SnMe₄ catalyst was different from that in the ethene initially, and [¹³C₂]propene formed in this reaction was composed of randomized 1,2-, 1,3-, and 2,3-[¹³C₂]propene; this suggests that the homologation reaction process is independent of the metathesis reaction.
