Katritzky salts have emerged as effective alkyl radical sources upon metal- or photocatalysis. These are typically prepared from the corresponding triarylpyrylium ions, in turn an important class of photocatalysts for small molecules synthesis and photopolymerization. Here, a flow method for the rapid synthesis of both pyrylium and Katrizky salts in a telescoped fashion is reported. Moreover, several pyrylium salts were tested in the photoinduced RAFT polymerization of vinyl ethers under flow and batch conditions.

1-((E)-3-(4-bromophenyl) -1-phenylallylidene)-2-(m-tolyl)hydrazine (4) was synthesized and characterized for structural elucidation by spectroscopy (FT-IR, 1H NMR, and 13C NMR) and single crystal X-ray diffraction. In the title compo

A series of blue fluorescent materials containing electron accepting pyrimidine and electron donating bis(biphenyl)amine, diphenylcarbazole, and diphenylindolo[3,2,1-jk]carbazole moieties were synthesized in moderate yields, and their optical and electroc

The selective reduction of ?,¢-unsaturated carbonyl compounds was achieved to produce saturated carbonyl compounds with aqueous HI solution. The introduction of an aryl group at an ? or ¢ position efficiently facilitated the reduction with good yield. The reaction was applicable to compounds bearing carboxylic acids and halogen atoms. Through the investigation of the reaction mechanism, it was found that Michael-type addition of iodide occurred to produce ¢-iodo compounds followed by the reduction of C-I bond via anionic and radical paths.
