The noncumulative effect of methyl substituents on the rate of addition of benzeneselenenyl chloride to olefins11Organoselenium Chemistry IX, For Part VIII see GH …
The rates and products of addition of benzeneselenenyl chloride to ethylene and its six Me substituted derivatives have been determined in methylene chloride at 25°. Unlike the addition of 4-chlorobenzenesulfenyl chloride to this same series of compounds, the effect of Me groups on the rates of addition is not cumulative. Also the regiochemistry of the product is different. For arenesulfenyl chloride additions, products of anti-Markownikoff orientation ...
