The mechanism of action is likely to be similar to that of MSD, in that radical trapping by C=C addition yields a resonance-stabilized benzylic radical (Scheme 7) [31].
Chloro-containing compounds are known to form carbocations, especially for chloride bonded to allylic or benzylic groups (ref.
8,9) It is generally accepted that at least four reaction pathways are identified: (1) direct absorption of UV light by conjugated phenolic groups to form phenoxyl free-radicals, (2) abstraction of phenolic hydrogen as a result of aromatic carbonyl triplet excitation to produce a ketyl and phenoxyl free-radical, (10) (3) cleavage of nonphenolic phenacyl-[alpha]-O-arylethers to phenacyl phenoxyl free-radical pairs, (11) and (4) abstraction of benzylic hydrogen of the [alpha]-guaiacylglycerol-[beta]-arylether group to form ketyl free-radicals which then undergoes cleavage of the [beta]-O-4 arylether bond to produce an enol and phenoxyl free-radical.
To take advantage of the fast and efficient photo-induced homolysis/heterolysis (5, 6) of benzylic ethers, we have functionalized several coumarins for this purpose.

9 ppm with two hydrogen in integration, it was unclear for us to assign it whether the alpha hydrogen on 16th carbon or the benzylic hydrogen on 10th carbon.
As a starting point, Louvain chemist Istvan Marko relied on studies in the late 1970s on the aerobic extraction of benzylic alcohols using copper-amine complexes as mediators.
Pincock has begun to obtain a real understanding of the factors that control the competition between homolytic and heterolytic photocleavage of benzylic substrates and is trying to apply these principles to develop synthetically useful procedures.
More examinations also resulted that in the case of benzylic and aromatic secondary amines such as benzylamine and N-methylaniline, the protocol was also efficient and produced the corresponding formamides in 88-90 % yields (entries 18 and 19).
Due to the benzylic chlorine, a great number of nucleophilic substitutions are made possible, leaving the double bond undamaged and providing new monomers that can be polymerized or copolymerized when the experimental conditions are well chosen (16), (17).
BIMSM can be cured efficiently via the benzylic bromine sites and requires only low levels of curatives for effective vulcanization.
This volume of the series consists of two chapters, on catalytic enantioselective aldol addition reactions, and benzylic activation and stereochemical control in reactions of tricarbonyl(arene)chromium complexes.
For further evaluating the one-pot chlorination/oxidation/Wittig olefination sequence, we decided to conduct the one-pot sequential chlorination/oxidation/Wittig olefination reaction under ultrasound conditions, using MnO2 as a selective, cost-effective, and environment-friendly oxidant agent for activated alcohols 1, such as allylic alcohol, propargylic alcoho, and benzylic alcohols, to give (Z)-a-chloro-a,b-unsaturated esters 3, Scheme 1.
