Radicals

The radicals should not have negative charges.— Preceding unsigned comment added by 216.164.142.143 (talk) 13:09, 17 April 2005 (UTC)

The discussion text seems correct. However, there is some ambiguity in the "Br.-radical" which suggests that perhaps the radical is negatively charged. Also, in the illustration, the radicals are clearly marked as being negatively charged. The neutral peroxide molecule does not break into two negatively charged radicals. That indicates a net input of two electrons. The radicals are neutral, and the illustration should be changed to reflect this.— Preceding unsigned comment added by 138.64.8.51 (talk) 13:51, 22 July 2005 (UTC)

Does not show anti-Markovnikov

Perhaps a better picture demonstrating that the reaction causes the Br to go to the less substituted carbon atom of the alkene would better illustrate the anti-Markovnikov regiochemistry. Andrew4010 04:44, 21 November 2006 (UTC)

I agree. Showing R³=R⁴=H would be more clear. I'll work on generating the image. Atomjockey (talk) 23:27, 19 June 2008 (UTC)

Extra oxygen atom in self-terminating radical cyclization scheme

In the step where the nitrite radical leaves from the ketyl, there is an abundant oxygen that wasn't there in the last step, likely to be caused by author's attempt to draw out the bond for the mechanism but forgetting to remove the oxygen from "ONO2" after.
