Fluorination with SbF3 has been used to prepare 1,1-difluoro-1-sitlacyclopent-3-ene, 1,1-difluoro-1-silacyclopen-2-ene, 1,1-difluoro-1-silacyclopen entane and a mixture of 1,1-difluoro-2-chloro-1-silacyclopentane and its 3-chloro isomer from the appropriate chlorosilanes. IR and NMR spectra of the products are reported.

The molecules 1,1-difluorosilacyclopent-3-ene (3SiCPF2) and silacyclopent-3-ene (3SiCP) have been synthesized and studied using chirped pulse, Fourier transform microwave (CP-FTMW) spectroscopy. For 3SiCP this is the first ever microwave study of the molecule and, for 3SiCPF2, the spectra reported in this work have been combined with that of previous work in a global fit. The spectra of each contain
