Stoichiometric functionalization of gold nanoparticles in solution through a free radical polymerization approach
A new simple concept for the stoichiometrical functionalization of nanoparticles based on free radical polymerization of vinyl protected nanoparticles is presented. To demonstrate this concept 2-bis(4-vinylphenyl)disulfane was synthesized and used in the synthesis of gold nanoparticles, leading to 4-vinylthiophenol functionalized nanoparticles. Simple free radical polymerization of these particles initiated by 4,4′-azobis-(4-cyanopentanoic acid) delivered nanoparticles with a singlecarboxyl group. These monofunctionalized gold nanoparticles were utilized for chemical preparation of gold nanoparticle dimers as well as for construction of gold nanoparticle arrays via binding to polyallylamine.

Oxidation reactions in segmented and continuous flow chemical processing using an N -(tert -Butyl)phenylsulfinimidoyl chloride monolith
A supported version of N-(tert-butyl)phenylsulfinim-idoyl chloride on a monolithic material is described, which can be incorporated into a flow chemical processing arrangement to oxidise a variety of substrates in both stoichiometric and catalytic processes to yield products in high yields and in high purity after in-line workup.
