    • Along these lines, it is worth noting that, in a control there is no evidence that 6 converts spontaneously to 8 under the reaction conditions employed for these studies. Specifically, the reaction of thiol with 6 is complete inside of 1 h. Within this timeframe, in the absence of thiol, there is no detectable oxidative or hydrolytic dcomposition of 6.
