The substitution reactions of pentachlorobenzenesulfenyl chloride with saturated alkanes were found to proceed by a free radical chain mechanism where the pentachlorobenzenethiyl radical is the predominant chain
Alkanes are saturated hydrocarbons which means that they are composed of only carbon and hydrogen atoms and there are only single bonds between carbon atoms. The alkanes undergo very few reactions which include free radical halogenation.Answer and Explanation: ...

Kinetic of free radical in-situ polymerization of glycidyl methacrylate (GMA), was studied in a complex evolutionary system: poly(vinyl chloride) (PVC) plastisols. A predictive model of conversion-time profile based on free radical mechanism was proposed and structure of the modified PVC system de...
After initiation, the reaction proceeded via a chain propagation mechanism: the addition of acyl radical to an electron-deficient alkene, followed by a hydrogen abstraction from aldehyde to release the product and regenerate the acyl radical [61]. Notably, under modified reaction conditions, a ...
To understand the mechanism, a series of control experiments were performed (Table 3). When 2.0 equiv of TEMPO was introduced under the standard reaction conditions, the yield of 3a was not significantly affected (see Supplementary Information for details), which points away from a radical pathway...

In the termination step, two free radicals join together creating one neutral ...
Recently, Liu and co-workers reported the development of a modular synthesis of alkynes through the reaction of esters with lithiated gem-diborylalkanes and aryl trifimides [4-CF3−C6F4−N(Tf)2] (Figure 1G). This method is excellent for the synthesis of a host of 13C-labeled alkynes...
