Oxidative Cross-Coupling of N-(2‘-Phenylphenyl)benzene- sulfonamides or Benzoic and Naphthoic Acids with Alkenes Using a Palladium−Copper Catalyst System under Air

Abstract: N-(2‘-Phenylphenyl)benzenesulfonamides react with acrylate esters accompanied via cleavage of the C−H bond at their 2‘-position in the presence of a catalyst system of Pd(OAc)2 and Cu(OAc)2 and a base under air to produce 5,6-dihydro-5-(benzenesulfonyl)phenanthridine-6-acetate derivatives in high yields. The reactions of benzoic acid with butyl acrylate and styrene can also give 3-[(butoxycarbonyl)methyl]phthalide and 3-phenylisocoumarin, respectively.

Synthesis of Acrylate and Methacrylate Block Copolymers Using Atom Transfer Radical Polymerization

Abstract: The synthesis of di- and triblock copolymers, involving methyl methacrylate (MMA), butyl acrylate, and methyl acrylate, using copper-based atom transfer radical polymerization (ATRP) is reported. It was found that poly(MMA) macroinitiator is able to initiate the ATRP of acrylic monomers. However, for polyacrylates to effectively initiate the ATRP of MMA, the end group should be a bromine atom and the catalyst CuCl; that is, halogen exchange should take place. ABA-type triblock copolymers, where B = poly(butyl acrylate) and A = poly(methyl methacrylate), were synthesized by growing the center block first using a difunctional initiator and then adding MMA to the ends.

Silica Nanoparticles as Surfactants and Fillers for Latexes Made by Miniemulsion Polymerization

Abstract: Polymer dispersions made of a variety of monomers, including styrene, butyl acrylate, and methyl methacrylate, were generated by the miniemulsion process in the presence of a coupling comonomer, a hydrophobe, and silica nanoparticles. Depending on the reaction conditions and the surfactants employed, different hybrid morphologies were obtained, comprising a “hedgehog” structure where the silica surrounds the latex droplet and provides stabilization even without any low molecular weight surfactant. In other parts of the composition diagram noncoupled structures as well as “raspberry” hybrids where whole clusters of silica nanoparticles are completely embedded in the polymer particle can be made. The resulting structures are promising for a number of applications, e.g. the increase of scratch resistance in water-based coatings.

Electrosteric Stabilization of Colloidal Dispersions

Abstract: The electrosteric stabilization of model colloidal dispersions is quantified through high-frequency rheometry and complementary techniques. Model aqueous dispersions with a poly(butyl acrylate)−pol...
