The insertion reactions of carboethoxycarbene on n-pentane, n-hexane, n-heptane and n-octane are studied. The products of each of the reactions were separated and identified by gaschromatography-mass spectrometry. The ratio between the products inserted on various C-atoms in each reaction is not coincident with that calculated from the reaction probability.This can be explained by a suggested reaction mechanism, in which the carbonium ion or freeradical, first formed during the abstraction of H-atom by the carbene, will rearrange partial-ly before recombination with the carboethoxy-methyl anion or free radical.
