~ujii et al. (1) have recently published the results of their work on the reaction between triethyl phosphite and bromo-and chloroacetglenes. We now communicate the results of our own studies on this reaction which we have referred to on a previous occasion (2). Gur approach is somewhat different
The kinetics of the thermal reaction between CF,OF and C,F, have been investigated between 20 and 75Β°C. It is a homogeneous chain reaction of moderate length where the main product is a mixture of the two isomers l-C,F,OCF, (68%) and 2-C3F,0CF3 (32%). Equimolecular amounts of CF,OOCF, and CsF,, are
