Alkenes micellar effects

Micellar effects on alkene bromination have been further studied and strong inhibition (105-106 fold) of the second-order reaction rate constants relative to those in water has been observed. The kinetics and the product distribution suggest that different olefins have different locations at the micellar surface. Kinetics in the presence of added NaBr and n-decane support this hypothesis160. Selective bromination of alkenes using bromine... 

Active oxygen transfer in the reactions of aldehydes and alkenes with hydrogen peroxide in carboxylic acid medium is possible both via catalyst and via carboxylic acid.220 Micellar effects on the cobalt(II)-catalysed oxidation of jn-nitroso-lV,lV-dialky-lanilines by H2O2 have been studied with a variety of surfactants of different charge types. Acid-catalysed oxidations of aryl sulfides and phosphorus esters of thiols with... 

Epoxidation of cyclooctene and other alkenes with Oxone (KHSO5) was promoted effectively in an aqueous micellar solution of an amphiphilic ketone (3.3).52 The amphiphilic ketone can be easily derived from hepta(ethylene glycol) monodecyl ether. 

The PET-induced dehalogenation of aromatics has been extensively investigated. It occurs in the presence of various donors, such as aliphatic and aromatic amines [82-92], alkenes and dienes [91, 93-94], mixed hydrides [95-97], hydroxides [98], carbanions [99-101]. In the absence of an added donor, a viable mechanism involves the excimer (singlet or triplet) and its collapse to oppositely charged radical ions followed by fragmentation of the radical anion [93, 102-104] (a micellar medium has an important effect in this case [103]).
