The rate constants for the reactions of OH radicals with CH 3 OCF 2 CF 3 , CH 3 OCF 2 CF 2 CF 3 , and CH 3 OCF(CF 3 ) 2 have been measured over the temperature range 250-430 K. Kinetic measurements have been carried out using the flash photolysis, laser photolysis, and discharge flow methods combine
Rate constants have been measured over the temperature range 245-419 K for the gas-phase reactions of the hydmxyl radical with the hydrofluorocarbons CHF,CF,CF,CHF, and CF&HFCHFCF2CF,. The Arrhenius expressions k (CHF,CF,CFzCHF,) =(7.80i3.40)X10-'3exp[-(1.51~0.26)~103/T] and k(CF,CHFCHFCF~CF,)=(4.21
Reactions of CF3N0 and (CF3)2N0 with hydrides of phosphorus, arsenic and germanium have in some cases led to interesting and novel unsaturated compounds containing P=N, As=N and Ge=N double
