The Knowledge and Use of the Bible in the Medieval Age
In attempting to show precisely to what extent the new learning pervaded the countries of Europe during the Middle Ages, and, specifically, just in how far the Bible was known among the clergy and laity, one must be careful to strive for the golden mean in interpreting a flood of literature which usually goes to one of two extremes. The first of these divergent opinions is the one mentioned above, that the Bible, as almost wholly unknown by the clergy and laity of the Middle Ages. And this would seem to be substantiated by no less an authority than Luther himself. There are several references in the Tischreden to the effect that the Holy Scripture was unknown to the people under the papacy in the later Medieval Age
A crystalline diazadiborinine radical cation and its boron-centered radical reactivity
Oneâelectron oxidation of 1,4,2,5âdiazadiborinine 1 has been studied. While the reaction of 1âa bearing phenyl groups on the B atoms with AgAl{OC(CF3)3}4 afforded a complex mixture, the same oxidation reaction with 1âb featuring bulky mesityl substituents on the B atoms rendered the corresponding cation radical 2âb as an isolable species. Xâray diffraction analysis, EPR spectroscopy, and DFT calculations of 2âb revealed the delocalization of the unpaired electron over the entire Ïâsystem of 2âb, as well as a large spin density (0.76 in total) on the two equivalent boron atoms. The chemical trapping reaction of 2âb with pâbenzoquinone and triphenyltin hydride afforded the dicationic species 3 containing two newly formed BâO bonds and the monocationic product 2bâH containing a BâH bond, respectively, thus confirming the boronâcentered radical reactivity of 2âb.MOE (Min. of Education, Sâpore
