Isomerization proceeds through a chain mechanism where the chain carrier may be thetert-C5H11+ion. In the presence of 3-methyl-1-butene, the initially formed (CH3)2CHCHCH3+ion isomerizes to the tertiary structure before producing the observed isomerization.Guy J. Collin...
Diatoms play a key role in the primary production and also in the export of carbon from the surface to the deep ocean. Their metabolism has the particularity to couple Si and C via the frustule synthesis. We studied the Si-OC interactions in the frustule and it possible impact on organic ...
