The combination of visible light, photovoltaics, and electrochemistry provides a convenient, inexpensive platform for conducting a wide variety of sustainable oxidation reactions. The approach presented in this article is compatible with both direct and indirect oxidation reactions, avoids the need for a stoichiometric oxidant, and leads to hydrogen gas as… (More)
PEG-modified diblock copolymer surfaces have been examined for their compatibility with microelectrode array based analytical methods. The use of PEG-modified polymer surfaces on the arrays was initially problematic because the redox couples used in the experiments were adsorbed by the polymer. This led the current measured by cyclic voltammetry for the… (More)
Carboxylic acids have been electro-oxidatively coupled to electron-rich olefins to form lactones. Kolbe decarboxylation does not appear to be a significant competing pathway. Experimental results indicate that oxidation occurs at the olefin and that the reaction proceeds through a radical cation intermediate.

ÐTwo constrained analogs of the tripeptide hormone thyroliberin (TRH) have been synthesized. In both, the HisPro peptide bond of the hormone has beenìocked' into a cis-conformation. In the ®rst analog, the constraint used was identical to the constraint used in an earlier trans-peptide bond analog that was a potent agonist for the TRH endocrine receptor… (More)
