Access to organometallic arylcobaltcorrins through radical synthesis: 4-Ethylphenylcobalamin, a potential "antivitamin B12"

Locked B12: 4-Ethylphenylcobalamin, a novel organometallic arylcobalamin, has been synthesized in a radical reaction. This vitamin B 12 antimetabolite features a strong Co-C bond, and represents a "locked" form of vitamin B12/s

Copper(I)-promoted trifluoromethylthiolation of arenediazonium salts with AgSCF3

An efficient method for trifluoromethylthiolation of arenediazonium salts has been developed in mild conditions with a stable and convenient AgSCF3. It provides a straightforward and convenient way for the synthesis of trifluoromethylthiolated compound from diazonium salts in moderate to good yields.

Effects of surface monolayers on the electron-transfer kinetics and adsorption of methyl viologen and phenothiazine derivatives on glassy carbon electrodes

Five organic redox systems were examined in aqueous electrolytes on polished and chemically modified glassy carbon (GC), to evaluate the effects of surface structure on the heterogeneous transfer rate constant, k°. Methyl viologen reduction to its cation radical exhibited a voltammetric peak potential difference which was insensitive to surface modification, with k°decreasing by only 50% when a chemisorbed monolayer was present. Methylene blue and three other phenothiazines adsorbed to polished GC, but the adsorption was suppressed by surface modification. For all four phenothiazines, chemisorbed or physisorbed monolayers of electroinactive species had minor effects on k°, with a compact nitrophenyl monolayer decreasing k°by 50%. This minor change in k°was accompanied by a major decrease in adsorption, apparently due to inhibition of dipole-dipole or π- π interactions between the phenothiazine and GC. Chlorpromazine oxidation to its cation radical was studied in more detail, under conditions where adsorption was suppressed. A plot of the natural log of the observed rate constant vs the monolayer thickness for a variety of chemisorbed monolayers was linear, with a slope of -0.22 A-1. The observations are consistent with a through-bond electron-tunneling mechanism for electron transfer to all five redox systems studied. The tunneling constant for CPZ of 0.22 A-1 is between that reported for electron tunneling through conjugated polyene spacers (0.14 A-1) and that reported for phenyl-methylene spacers (0.57 A-1), on the basis of long-range electron transfer in rigid molecules.
