In studies conducted in this laboratory dealing with the composition of the phosphatide isolated from the human tubercle bacillus, strain H-37, it was recognized early that an organic phosphoric acid of the formula C9H20014P2 could be separated in the form of the barium salt from the water-soluble cleavage products after the phosphatide had been saponified with alcoholic potassium hydroxide (I)...

The quenching of sonoluminescence from aqueous solutions by acrylic and methacrylic acids is dependent on whether the acid is ionised in solution, as controlled by the pH, but also by the frequency of ultrasound used.

Direct and selective replacement of carbon-hydrogen bonds with new bonds (such as C-C, C-O, and C-N) represents an important and long-standing goal in chemistry. These transformations have broad potential in synthesis because C-H bonds are ubiquitous in organic substances. At the same time, achieving selectivity among many different C-H bonds remains a challenge. Here, we focus on the functiona...
