radical polymerization (ATRP) of dimethyl(1-ethoxycarbonyl)vinyl phosphate (DECVP) was investigated in the presence of different catalyst systems and initiators. Polymers with controlled molecular weight and relatively low polydispersity (PDI < 1.5) were obtained throughATRP initiated with ethyl 2-bromoisobutyrate (EBriBu) in the presence of Cu(I)Cl/2,2‘-bipyridine (bpy).

The formation of protein-decorated nanosized polymeric particles is described. Annexin-A5 protein binding to micellar aggregates having poly((1-ethoxycarbonyl)vinylphosphonic diacid) (PECVPD) and poly(n-butyl acrylate) (PBuA) as corona- and core-forming segments, respectively, was evidenced by Static and Dynamic Light Scattering (SDLS), cryo-Transmission Electron Microscopy (cryo-TEM), and Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) experiments. These new objects find potential applications, for example, in micelle-mediated target drug delivery and controlled fabrication of biochips.
Two carbon homologation of carboxylic acids via carbon radicals generated from the acyl derivatives of N-hydroxy-2-thiopyridone: Synthesis of Cn+2 α-keto-acids from Cn acids. (The ‘three carbon’ problem).
Reaction of olefins containing a three carbon atom chain with carbon radicals generated from carboxylic acids furnishes adducts that are precursors of the corresponding two carbon atom longer alpha-keto-acids. The keto-acids are furnishes in high overall yield.
