Herein, we report a solvent- and metal-free methodology for the alkoxy-chalcogenylation of styrenes, using molecular iodine as a catalyst, DMSO as a stoichiometric oxidant, and different nucleophiles under microwave irradiation. This eco-friendly approach afforded the desired products in good to excellent yields in only 10 min. In addition, using the same protocol, we carried out the cyclization reaction of relevant molecules, such as lapachol derivatives.

Using potassium iodide as a catalyst and m-chloroperbenzoic acid as an oxidant, an efficient catalytic procedure has been developed for the azidoselenenylation of alkenes with sodium azide and diselenides, and a series of corresponding β-azidoselenides, m
N-Phenylselenosaccharin (NPSSac): a new electrophilic selenium-containing reagent
Tingoli, Marco,Diana, Rosita,Panunzi, Barbara
, p. 7529 - 7531 (2007/10/03)
A new reagent N-phenylselenosaccharin (NPSSac) was simply prepared and used as a source of the electrophilic phenylselenyl group. This relatively stable new compound was able to react with a series of electron rich organic molecules like alkenes in the pr
Electrophilic azido selenenylation of alkenes. A simple synthetic route to racemic taxol side chain
Tiecco, Marcello,Testaferri, Lorenzo,Temperini, Andrea,Bagnoli, Luana,Marini, Francesca,Santi, Claudio
, p. 2167 - 2179 (2007/10/03)
Simple alkenes react with PhSeOTf and NaN3 in MeCN to afford β- phenylseleno azides as the result of a stereospecific trans addition. The regioselectivity of the process is determined by the structure of the alkene.
Novel Azido-phenylselenenylation of Double Bonds. Evidences for a Free Radical Process
Tingoli, Marco,Tiecco, Marcello,Chianelli, Donatella,Balducci, Roberta,Temperini, Andrea
, p. 6809 - 6813 (2007/10/02)
A simple and mild azido-phenylselenenylation of terminal alkenes, which proceeds with complete anti-Markovnikov regioselectivity, has been developed.This reaction occurs when the alkenes are treated with (diacetoxyiodo)benzene, sodium azide, and diphenyl
PHENYLSELENIUM AZIDE ADDITION TO ALKENES. A NEW AND STEREOSPECIFIC INTRODUCTION OF Se AND N INTO ORGANIC MOLECULES.
Hassner, Alfred,Amarasekara, Ananda S.
, p. 5185 - 5188 (2007/10/02)
The first examples of direct introduction of PhSe and N3 functions by addition to olefins are reported.The addition of PhSeN3 to simple alkenes, as well as to activated alkenes takes place in the absence of a catalyst.The reaction proceeds stereospecifica
