In 1965 Seshardri et al. described the isolation of an unknown terpenoid acid B obtained from the lichens of Lobaria retigera in the western Himalayas [8]. (Note that this annotation bears no relation to the subsequent nomenclature later defined by Corey and Shibata.) Four collections had been made in the summer of 1962 from under the Rutba plants in the Valley of Flowers (12,500 feet) and on the way to Hemkund Lokpal (13,500 feet) and from underneath rocks and from pine trees in Ganghariya (10,000 feet). The samples were subjected to a series of increasingly polar extractions (petroleum ether, diethyl ether, acetone). The unknown terpenoid acid B was present in all petroleum ether extracts, except that of the sample obtained from the Valley of Flowers, in compositions ranging from 0.47 % to... 

The soluble metabolites excreted from animals dosed by injection were collected on AmberliteR XAD-4 resin, the resin eluted sequentially with diethyl ether, acetone, and methanol, and the solutes separated by thin-layer chromatography on silica gel and quantitated by liquid scintillation counting.

The product is a yellow solid that is air sensitive. It decomposes at 210 °C without melting. It is soluble in hot toluene but the solubility is low. It is insoluble in THF, diethyl ether, acetone, CH2C12, pyridine, and methanol. The IR spectrum (KBr disk) contains a strong, sharp peak at 1560cm-1. The product reacts with carbon monoxide affording glutarimide in a 66% yield and Ni(CO)3(tcyp).

All the naphthylpyrroles (14-17) are crystalline substances (see Table XIII) soluble in diethyl ether, acetone, chloroform, DMSO, poorly soluble in ethanol, hexane, and insoluble in water. Typical H-NMR spectra of these pyrroles are presented in Table XVI. 

The results of the evaluation showed the RIs to vary only slightly with the different operator, the different instrument of the same manufacturer with the same column in one or several laboratories, column individuals of the same manufacturer, solvents (diethyl ether, acetone, and ethyl acetate), and use of a multistep temperature program. There were no significant differences in the reproducibility of RIs determined using different index standard series. M-standards are relatively nonpolar and differ little in their behavior from C-standards on a nonpolar SE-54 phase. When the number of index standard components was reduced, the RI values...

Hydridobis[ s-vinylenebis(diphenylphosphine)] cobalt(l) is a red crystalline solid that is unstable in air both in the solid state and in solution. The complex is soluble in tetrahydrofuran (9.2 X 10-3 mole/L, at 20°), toluene (10.2 X 10 3 mole/L), chloroform (6.3 X 10-3 mole/L), dichloromethane (1.6 X 10-3 mole/ L), and benzene (8.4 X 10-3 mole/L). It is insoluble in ethanol, diethyl ether, acetone, and pentane. The infrared spectrum in Nujol mull shows a band at 1885 (m) cm-1, attributable to the Co-H stretching vibration. 

Tetraphosphorus hexamethylhexaimide is a moisture-sensitive, white crystalline solid melting at 122 to 123 and boiling at 303 to 304 at 737 mm.

Hexane or light petroleum ether, chloroform, benzene, and toluene are most often the major components of the mobile phase, whereas smaller proportions of diethyl ether, acetone, methanol, ethanol, or acetic acid are added as modifiers. Chloroform-methanol and hexane-acetone mobile phases reportedly provide very good separations. Often more than one development is required for reliable resolution. The separation starts with the most polar phase and proceeds, after drying between runs, with mobile phases of gradually decreasing polarity. Highly unsaturated components are resolved first and do not move further with subsequent developments when the more saturated components are separated.
