In this paper we report on spin-orbit coupling induced mag­ netokinetic effects on the free radical yield of triplet elec­ tron transfer reactions. From the magnetic field dependence ob­ served in a variety of mixed solvents the solvent dependent dy­ namics of short-lived triplet exciplexes is quantitatively de­ duced.

Regioselective S-acylation of coenzyme A (CoA) is achieved under aqueous conditions using various aliphatic and aromatic carboxylic acids activated as their methyl acyl phosphate monoesters. Unlike many hydrophobic activating groups, the anionic methyl acyl phosphate mixed anhydride is more compatible with aqueous solvents, making it useful for conducting acylation reactions in an aqueous medium.

We used chemical force microscopy (CFM) to study adhesive forces between surfaces of epoxy resin and self-assembled monolayers (SAMs) capable of hydrogen bonding to different extents. The influence of the liquid medium in which the experiments were carried out was also examined systematically. The molecular character of the tip, polymer, and liquid all influenced the adhesion. Complementary mac...
