Austausch der Aminreste in den inneren Komplexsalzen der Schiffschen Basen

Vapor pressures of the isotopic waters and ices

“…The correction for the molar volume isotope effect is easily evaluated, at least for D20, from the data cited in the review by Whalley. 15 The correction is completely negligible (<1 X 10~4 in In (P'/P)) for all temperatures below 500°K. We shall make the plausible assumption that this is true for the other isotopic isomers as well and drop it from consideration.…”

Transition metal complexes of a cationic phosphine ligand

“…After four batches of crystals of (P-P+)C1 were isolated from successively smaller volumes of ethanol, the remaining solvent was removed by vacuum distillation, and the viscous oil that remained was identified as the diphosphine C29H29C1P2. 13 Preparation of the Perchlorate Salt of (P-P+).-Equivalent quantities of the phosphetanium chloride (1 mmol, 0.48 g) and lithium perchlorate (1 mmol, 0.11 g) were combined in 10 ml of refluxing ethanol. When the solution cooled to room temperature, white crystals separated; these were dried in vacuo.…”
