Manganese carbonyl-mediated reactions of azabutadienes with phenylacetylene, methyl acrylate and other unsaturated molecules [PDF]
, 2004 Reaction of PhCH₂Mn(CO)₅ with l,4-di-aryl-1-aza-1,3-butadienes gave substituted pyrrolinonyl rings which were η⁴-coordinated to a Mn(CO)₃ group. These are formed by intramolecular CO insertion into a (non-isolated) cyclomanganated intermediate, followed ...

Thermal Decomposition of Vicinal Dinitroalkanes
CHIMIA, 1988 Three sym-tetraalkyl-dinitroethanes 1-3 have been decomposed in solution at 180 to 215 °C. The alkylated 1,3-butadienes 10,12, and 13 are formed by elemination of HNO2.

Electron correlation effects in electron-hole recombination in organic light-emitting diodes [PDF]
, 2002 We develop a general theory of electron--hole recombination in organic light emitting diodes that leads to formation of emissive singlet excitons and nonemissive triplet excitons.

Arylthio-substituierte Nitrilylide aus der Thermolyse von 4-Arylthio-3-oxazolin-5-onen
CHIMIA, 1984 Thermolysis of 4-arylthio- and 4-benzylthio-3-oxazolin-5-ones leads to arylthio- and benzylthio-substituted nitrile ylides, which undergo 1,3-dipolar cycloadditions with reactive dipolarophiles to give 5-membered aza-heterocycles (Schemes 1 and 2).
