✦ Synopsis


The thermal dehydrochlorination has been studied CF ClCH : CF " CH Ο© HCl 2 3 2 2 in a static system between 597 and in the presence of CCl 4 , C 2 Cl 6 , CF 2 "CH 2 , HCl, and 664 K CF 3 CH 3 . A kinetic radical and molecular reaction model has been developed. In addition to describing earlier results on the acceleration of the pyrolysis by CCl 4 and the further acceleration by HCl, this model describes quantitatively up to conversions of 20% (i) the dependence of the catalytic effect of CCl 4 at low concentrations, (ii) the stronger catalytic effect of C 2 Cl 6 , and (iii) the inhibitory effect of added CF 2 CH 2 and CF 3 CH 3 when CCl 4 is used as a catalyst.

A new insight into the contested origin of the absence of radical reaction in the pyrolysis of CF 2 ClCH 3 is given. This chain reaction would be too slow compared with the molecular reaction because of a too slow homogeneous initiation leading to a too fast wall recombination of the Cl atom chain c

Rate constants for the reaction of 1-chloro-2,3-epoxypropane with p-cresol in the presence of basic catalysts were studied at the temperature range of 71 -100Β°C. It was found that in the presence of sodium p-cresolate, three consecutive reactions proceeded giving the following products: 1-chloro-3-

The mechanism of 1,2-addition reactions of HF and HCl to Si=Si, Si=C, and C=C bonds has been investigated by ab initio quantum chemical methods. Geometries and relative energies of the stationary points and all the transition states were determined by using the MP2/6-311++G(d,p), B3LYP/6-311++G(d,p)
