Green protocol for conjugate addition of amines to p-quinones accelerated by water
Yadav, Jhillu S.,Reddy, Basi V. Subba,Swamy, Tallapally,Shankar, Kattela Shiva
experimental part, p. 1317 - 1320 (2009/12/04)
Amines undergo smooth conjugate addition to p-quinones in H2O at ambient temperature in the absence of a catalyst to produce 2-aminoquinones in excellent yields. Significant rate acceleration of this reaction is observed in H2O compa
Studies on Quinones X. On the Reaction of p-Benzoquinone with Secondary Aliphatic Amines

, p. 901 - 909 (2007/10/03)
p-Benzoquinone (1) reacts with dialkylamines 2a-d to 2-dialkylamino-p-benzoquinones 3, 2,5-bis-dialkylamino-p-benzoquinones 4, 2-dialkylamino-8-hydroxydibenzofuran-1,4-quinones 5, and in pyridine also to 2-dialkylamino-5-p-hydroxy-phenoxy-p-benzoquinones 6. A method affording almost exclusively 3 has been developed which is also applicable to compounds 2e-h.
Synthesis and Photolysis of 2-Dialkylamino-1,4-benzoquinones and 2-Dialkylamino-1,4-anthraquinones

Reactions of dimethylamine, diethylamine, piperidine, and morpholine with 1,4-benzoquinone and 1,4-anthraquinone yield corresponding 2-dialkylamino-, 2-piperidino-, and 2-morpholinoquinones.The quantum yields of photoinduced transformations of these compounds in toluene have been determined.The quantum yields in the case of 2-dialkylamino-1,4-anthraquinones are by a factor of 2-3 higher than in the case of 2-dialkylamino-1,4-benzoquinones.
Synthesis and Spectral Properties of New Fluorescent Probes for Potassium
Crossley, Roger,Goolamali, Zia,Gosper, Jeffrey J.,Sammes, Peter G.
, p. 513 - 520 (2007/10/02)
Studies on the preparation and properties of two new, selective fluorescent probes CD18, 1 and C18, 2 for potassium are described.The probes incorporate the 1,10-diaza-18-crown-6 chelating group for the ion and the coumarin group as the fluorophore.The probes are compared with the known reagent PBFI.C18 shows considerably greater selectivity for potassium over sodium than PBFI.
