Solid-state photochemistry of crystalline pyrazolines: Reliable generation and reactivity control of 1,3-biradicals and their potential for the green chemistry synthesis of substituted cyclopropanes
Shiraki, Saori,Vogelsberg, Cortnie S.,Garcia-Garibay, Miguel A.
, p. 1929 - 1937 (2013/01/16)
To expand on the limited number of examples that exist in the literature for the solid-state photodenitrogenation of azoalkanes, a series of crystalline 7-alkyl-2,3,7-triazabicyclo[3.3.0]oct-2-ene-6,8-diones with varying 4,4-substituents were prepared. Th

Louhichi, Nesrine,Haouas, Amel,Hamadi, Naoufel Ben,Msaddek, Moncef
experimental part, p. 215 - 218 (2012/03/10)
The reaction of diphenyldiazomethane with N-substituted maleimides produces Δ 1-pyrazolines. The photolysis of Δ 1-pyrazolines leads to cyclopropanes. 2011 · Copyright by Walter de Gruyter.
Reactions of aliphatic diazo compounds: IV. Reaction of diphenyldiazomethane with substituted imides of maleic and itaconic acids
Molchanov,Diev,Kostikov
, p. 259 - 263 (2007/10/03)
Diphenyldiazomethane regioselectively adds to 2-R-substituted maleimides to yield 1-pyrazoline derivatives, 1-R-7-aryl-6,8-dioxo-4,4-diphenyl-2,3,7-triazabicyclo[3.3.0]oct-2-enes that on heating liberate nitrogen to afford substituted 3-azabicyclo[3.1.0]h
REACTIVITY OF SUBSTITUTED DIAZOMETHANES IN 1,3-DIPOLAR CYCLOADDITION TO N-ARYLMALEIMIDES AND ARYLETHENES
Samuilov, Ya. D.,Movchan, A. I.,Solov'eva, S. E.,Konovalov, A. I.
, p. 1985 - 1988 (2007/10/02)
The reactivity of phenyl- and diphenyldiazomethanes in 1,3-dipolar cycloaddition to N-arylmaleimides and also of diphenyldiazomethane in reaction with aryl ethenes was studied.It was shown that all the investigated reactions are of the "1,3-dipole-donor,
