13C and 15N photo-CIDNP effects were determined for the reversible electron transfer from pyrene to arene diazonium salts on excitation of the charge transfer band at 360 nm. The diazonium salts being the products of back electron transfer ("cage products") show enhanced absorption for 13C(1) and the 15N-enriched diazonium group, whereas the escape products, ArH or löN2, respectively, yield emi...

In general, in the production of projection slides, one is limited to the use of s tandard lantern slide plates. If the original electron micrograph negatives vary in contrast, it is often difficult to produce, within an acceptable range of density, a series of slides for projection. In an a t tempt to overcome this difficulty, diazotype color films have been tested as an alternative to the sta...

an one-pot method has been developed for the synthesis of azo dyes via sequential diazotization–diazo coupling of aromatic amines with coupling agents at room temperature in the presence of bi(no3)3. 5h2o. short reaction times, high yields, a clean process, simple methodology, easy work-up and green ‎conditions are advantages of this protocol.‎

The electrochemical and chemical modification of carbon by reduction of diazonium salts attracted a lot of interest in the past decade. The major disadvantage of the modification approach based on aryl diazonium salt is that the synthesis of the salt is required. Indeed, the synthesis and isolation of the diazonium salt are not always straightforward. The synthesis is commonly carried out in ac...

The covalent functionalization of the external wall of C(60)@SWCNT peapods, by in situ generated aryl diazonium salts, assisted by microwave irradiation is reported. Spectroscopic, thermal and microscopy characterization was performed. Electrochemistry revealed the three reversible reductions of encapsulated C(60), however, shifted towards positive potentials when compared with those of intact ...

We developed a visible detection system for antibody-catalyzed retro-aldol-retro-Michael reactions. Aldolase antibody 38C2 catalyzed the reaction of substrate 1 to provide 6-bromo-2-napthol that forms a visible colored azo dye with diazonium salts. This system has potential for the screening of novel catalysts.

An environmentally friendly Matsuda-Heck reaction with arenediazonium tosylates has been developed for the first time. A range of alkenes was arylated in good to quantitative yields in water. The reaction is significantly accelerated when carried out under microwave heating. The arylation of haloalkylacrylates with diazonium salts has been implemented for the first time.
