Synthesis and characterisation of new silicon-perfluoropropenyl compounds.

ABSTRACT: Novel, stable silicon-pentafluoropropane compounds have been synthesised from the direct reaction of hydrofluorocarbons Z-CFH[double bond, length as m-dash]CFCF₃ (Z-HFC-1225ye) with ⁿ BuLi, followed by appropriate silicon-halide. The compounds have been characterized by multinuclear NMR studies (¹⁹F, ¹H, ²⁹Si and ¹³C), DFT studies and structural confirmation was obtained by X-ray diffraction. Based on the outcome of treating synthetic silicon-pentafluoropropene compounds with different nucleophilic sources ( ⁿ BuLi, ^t BuLi, MeLi, and PhLi) and computed for this reaction DFT energetics, it is clear that the C-F _trans bond is more active than C-F _<
