However, the catalytic mechanism of Lewis acid has never been reported. We consider that this reaction may be accelerated through the formation of a charge transfer complex. Therefore,展开更多

INTRODUCTION The oxidation of saturated hydrocarbons Was, in the past, concentrated in the oxidation of paraffin into mixed fatty acids, which were then used in industry in soapmaking, etc. Simple gaseous hydrocarbons, such as from methane and ethane were also used as subjects in the kinetical study of oxidation reactions. Reports of work focusing on the studies of synthesis of oxygen derivatives directly from oxidation of single alkane were few.展开更多

An extraordinary result was obtained and it was that the product contained only primary (prim-) and secondary (sec-) but no tertiary(tert-) chlorides. We explained this fact as that one part of展开更多
