Reactions of Lucigenin in protic solvents in the presence of amines

Journal f�r Praktische Chemie/Chemiker-Zeitung, 1994
Lucigenin (N,N′-dimethyl-9,9′-biacridinium nitrate) 1 on heating under reflux in protic solvents in the presence of amines gives rise to the N,N′-dimethyl-9,9′-biacridylidene 2 (DBA) or protected hemiaminal N-methoxymethyl-9,9′-bi-acridylidene 3.

Substitution reactions of trans-[PtL2Cl2] in protic solvents

Journal of Inorganic and Nuclear Chemistry, 1966
Abstract An investigation of the nucleophilic substitutions of trans-[PtL2Cl2], L = P(C2H5)3 or piperidine, with 36Cl−, Br−, N3−, I− and SCN− in methyl, ethyl and butyl alcohols at 40°C is reported. The rate determining step is the substitution of the first chloride atom. The pseudo-first order rate constants, kobs.sec−1, are consistent with the two

Gas-Phase Metal Trications in Protic Solvent Complexes

Journal of the American Chemical Society, 2002
In the first observation of triply charged metal ions microsolvated by protic ligands, gas-phase complexes of 11 different metal trications with diacetone alcohol were generated using electrospray ionization. These species were found to exist for at least five to eight ligands, depending on the metal.

Aminolysis of oxime ethers in protic and aprotic solvents

Journal of the Chemical Society, Perkin Transactions 2, 1989
Reactions of oxime ethers with the primary amines, n-propyl-, n-butyl-, n-pentyl-, and n-hexylamine in DMSO, DMF, and MeCN are strongly catalysed by general bases. The observed secondorder rate constants (kA) exhibit a curvilinear dependence on amine concentration leaving a positive intercept.
