Arylation reactions: The Photo-S(sub N)1 path via phenyl cation as an alternative to metal catalysis
Article Abstract:
Photo(sensitized) cleavage of benzenediazonium salts as well as, when an electron-donating substituent is present, of aryl chlorides, fluorides, mesylates, triflates and phosphate leads to the corresponding phenyl cations in the triplet state. These intermediates add selectively to alkenes, alkynes and hetero arenes, giving arylation products in a good yield.

Advances in nitrogen transfer reactions involving aziridines
Article Abstract:
Efforts towards the synthesis and functionalization of aziridines, involved in nitrogen transfer reactions, are highlighted. The electrochemical aziridination of olefins, the acid-catalyzed ring opening of aziridines and the development of transition metal mediated nitrogen allylation, arylation and alkenylation of unprotected aziridines are investigated.

Catalysis of stannane-mediated radical chain reactions by benzeneselenol
Article Abstract:
The development of the catalysis of stannane-mediated radical chain reactions by benzenselenol, which is generated in situ by reduction of diphenyl diselenide with tributylin hydride, is described. The catalytic reaction demonstrates that a single, inefficient propagation step may be advantageously replaced by two well-matched steps.
