“…Furthermore, the E, values of both compounds do not deviate from the correlation between El us. o1 or o*, indicating the absence of abnormality such as steric effects (14). We therefore believe that k, for t-butylamine is not low but that k, for n-hexylamine is high.…”

Rateconstants for quenching of triplet excited acetone by primary and tertiary amines in solution have been measured directly by flash and pulsed laser techniques. The rate constants were found to be independent of solvent dielectric constant over the range E 1.9 to e 80, but were influenced by amine ionization potential. The results are interpreted as supporting a charge-transfer model for the quenching of triplet ketones by tertiary amines. The intervention of free ions in the quenching process is discussed. Free energy calculations indicate that electron transfer from N.N-dimethylaniline to triplet ketones is exothermic but is slightly more favorable for triplet aromatic ketones than for triplet acetone. Evidence for direct hydrogen atom transfer was obtained for quenching of triplet acetone by tl-hexylamine.

“…A number of early studies reported that the ionization energies of alkanethiols, 27 alkyl alcohols, 28 alkyl halides 29 and alkylamines 30 were linear functions of the inductive substituent constant I for the alkyl group as evaluated by Taft and Lewis. 31 More recent evaluations 4,7,9 of inductive substituent constants concluded that I for alkyl groups are essentially zero.…”

Zur Ableitung von Informationen über die Ligandeneigenschaften der Phosphane MenP(CF3)3−n (n = 0–3; Me = CH3) werden die bei der Synthese der BX3‐Addukte (X = H, Hal, Me) und der Komplexe M(CO)5L bzw. M(CO)4L2 gewonnenen Erkenntnisse und spektroskopischen Daten (IR, NMR) kritisch ausgewertet und mit den Bindungsmodellen von DOBSON u. Mitarb. [9] sowie BARBEAU u. Mitarb. [10] verglichen. Die Ergebnisse stützen die Beschreibung der MP‐Bindung als Kombination aus σ‐Donor‐ und π‐Akzeptoranteil.
