The reaction between cycloalkanes and halocarbons, such as CCl 4 , to yield cycloalkyl halides proceeds in good yield in the presence of a range of metal carbonyl complexes. Kinetic evidence suggests that the metal complexes act as efficient initiators of radical chain processes....
The reaction of a halogen with an alkane in the presence of ultraviolet (UV) light or heat leads to the formation of a haloalkane (alkyl halide). An example is
1 The function of NEt3. a. The side reactions when L9 was employed in the reaction. b. The possible mechanism for the side product formation. The oxygenation and amination product were formed via reductive elimination from PdIV. c. NEt3 acted as a liable ligand to accelerate the ...
A better reformulation of Markovnikov’s rule is therefore that addition of HX to alkenes will proceed through the most stable carbocation, which is generally the more substituted carbon of the alkene. (Note that H-Br with peroxides (RO-OR) operates through a different reaction mechanism – see...

When trying to make alkanes reactive, we must first perform aradical halogenationto add a halogen and allow for further reactions to take place. The oneexceptionwe must remember is that when doing a radical chlorination in particular we can only perform this reaction when asingle type of hydrog...

As we discussed in thelast post on radicals, bromine radicals are considerably more selective than chlorine radicals in the halogenation of alkanes. Why? As we saw, the detailed answer involves looking at reaction energy diagrams, the Hammond postulate, and the Arrhenius equation. ...
