The hindered carbon-centered radicals are most suited as mediators in the polymerization of 1,1-disubstituled monomers e.g. MMA,78,95 other methacrylates and MAA,06 and AMS97). Polymerizations of monosubstituted monomers are not thought to be living. Dead end polymerization is observed with S at polymerization temperatures <100°C.98 Monosubstituted monomers may be used in the second stage of AB block copolymer synthesis (formation of the B block).95 However the non-living nature of the polymerization limits the length of the B block that can be formed. Low dispersities are generally not achieved.

Since new carbonyl compounds of Ti, Zr, and Hf and their accompanying chemistry are appearing at a steady rate in the literature, it seems appropriate at this time to bring this rapidly growing area into perspective. In this review we will endeavor to categorize all reported group 4B metal carbonyls including their synthesis, formation,1 structure, spectroscopic...

With the growing importance of modern combinatorial chemistry, additional benefits accrue for catalyst systems that readily adapt to 96 well or higher density synthesis formats. 

Insulin is a polypeptide hormone that consists of two peptide chains bonded by two disulfide bonds. The two chains are designated A and B. The A chain consists of 21 amino acids with a third internal disulfide bond, and the chain contains the remaining 30 amino acids. All vertebrates produce insulin and the structure is similar in these species. For example, the insulin produced in humans and porcine species differs by only one amino acid, and humans and bovine insulin differ by three amino acids. Insulin plays a crucial role in several physiological processes. These include the regulation of sugar in the body, fatty acid synthesis, formation of triglycerides, and amino acid synthesis.
