CO2 LASER INDUCED REACTIONS OF CHLOROTRIFLUOROETHENE AND 1,2-DICHLORODIFLUOROETHENE WITH SILANE

Article abstract of DOI:10.1016/0584-8539(90)80149-S

Gas-phase reactions in ClFC=CF2 / SiH4 and ClFC=CFCl / SiH4 mixtures at total pressure arround 1 Torr induced by pulsed CO2 laser radiation yield different products depending on whether the single laser irradiating wavelength is tuned to absorption band of olefin or silane.Channels assumed to explain variety of products are multiphoton dissociation of the olefin into carbenes, carbenes recombination and addition to parent olefin, substitution of halogen in transient carbenes by hydrogen of silane, and 1,2-migration of halogen in transient CFCl=CF(.) radical.
