The acidity constant of protonated 2-[bis(2-hydroxyethyl)amino]-2(hydroxymethyl)-1,3-propanediol (Bistris) has been measured. The influence of hydroxo groups on the basicity of Bistris and related bases is discussed. The interaction of Bistris with t

The qualities of di-2-pyridyl ketone (DPK) in aqueous solution (I = 0·1, NaClO4; 25°) were studied by potentiometry and spectrophotometry in the absence and presence of metal ions. The acidity constants of DPKH+ ( p K A 1 = 3·06 ) and of the gemin

The aromatic-ring stacking interactions between the indole moiety of L-tryptophan and the purine or pyrimidine moieties of AMP2− or CMP2+, respectively, were studied by 1H NMR spectroscopy. Under the influence of increasing concentrations of L-tryt

Reaction of photogenerated (η5−C5H5)2W2(CO)4 with acetylene at 25°C yields a complex of the formula (η5-C5H5)2W2(CO)4(C2H2). The crystal structure of the complex shows it to have a tetrahedrane-like W2C2 core. The C—C bond distance of the C2H2
