Let’s start withthis classicfrom 1971 in theJournal of Organic Chemistry. A paper with the title ‘Comparative mobility of halogens in reactions of dihalobenzenes with potassium amide in ammonia’ doesn’t sound like it promises much in the way of literary sparkle, but take a look at how...
The carbapenem derivative of this invention is represented by Formula I: ##STR4## wherein R1is hydrogen or a hydroxy protecting group; R2is substituted or non-substituted lower alkyl; R3is hydrogen, an inorganic or organic base, or a carboxy protecting group; and R4is a group represented by...
In semi-logarithmic coordinates, gradients of between 5 and 22 eV−1 for the Urbach edge in this region are characteristic of many inorganic amorphous semiconductors and dielectrics [48,52,55,56,57,58,59]. For example, the amorphous semiconductor IV-compound Ge16As35Te28 Si21 has an ...
