Infrared photoreaction of 2-chloroethyltrifluorosilane
Infrared laser dissociation of 2-chloroethyltrifluorosilane has been studied in light of silicon isotopes separation. The reaction occurs via beta-elimination mechanism to yield ethylene and chlorotrifluorosilane as products. The dissociation has a relatively low energy barrier what was confirmed by high-level quantum chemical calculations. High enrichment of 30Si isotope was demonstrated.
► Infrared laser induces a reaction of 2-cloroethyltrifluorosilane. ► The reaction has a molecular beta-elimination mechanism. ► Silicon isotopes separation is realizable.
