Distinguishing Between Pathways for Transmetalation in Suzuki-Miyaura Reactions

Distinguishing Between Pathways for Transmetalation in Suzuki-Miyaura Reactions Brad P. Carrow and John F. Hartwig* J. Am. Chem. Soc. 2011, 133, 2116. The Suzuki-Miyaura cross-coupling reaction (Fig. 1) is definitely one of the most important reactions in synthetic chemistry, especially in industrial and medical settings.   So one would think that the mechanism of this classic...

Activating efficient phosphorescence from purely organic materials by crystal design

Journal: Nature Chemistry Authors: Onas Bolton, Kangwon Lee, Hyong-Jun Kim, Kevin Y. Lin, and Jinsang Kim Affiliation: University of Michigan, Ann Arbor Phosphorescent materials, those which emit light long after excitation, have found increasing use in organic electronics as well as chemical and biological sensing. Perhaps the most well-known phosphors are the greenish glow-in-the-dark materials... Continue Reading →

Cu(II) coordination in Proteins

Coordination Features and Affinity of the Cu2+ site in the alpha-Synuclein Protein of Parkinson’s Disease Dudzik, C.G.; Walter, E.D. and Millhauser, G.L. Biochemistry ASAP Alpha-synuclein proteins, concentrated in neurons in the human body, are composed of mostly hydrophobic residues. The hydrophobicity of the protein results in frequent aggregation or ‘clumping together’ of multiple alpha-syn proteins... Continue Reading →
