Journal ArticleDOI
Reaction of azides with dichloroindium hydride: very mild production of amines and pyrrolidin-2-imines through possible indium-aminyl radicals.
Luisa Benati,Giorgio Bencivenni,Rino Leardini,Daniele Nanni,Matteo Minozzi,Piero Spagnolo,Rosanna Scialpi,Giuseppe Zanardi +7 more
TL;DR: A rationalization of the overall experimental data cannot exclude the occurrence of competitive radical and nonradical pathways, but certain results are soundly consistent with the intermediacy of indium-bound nitrogen-centered radicals.
Journal ArticleDOI
Radical reduction of aromatic azides to amines with triethylsilane
Luisa Benati,Giorgio Bencivenni,Rino Leardini,Matteo Minozzi,Daniele Nanni,Rosanna Scialpi,Piero Spagnolo,Giuseppe Zanardi +7 more
TL;DR: Aromatic azides are inert toward triethylsilane under thermal conditions in the presence of a radical initiator, but in the Presence of additional catalytic amounts of tert-dodecanethiol, they afford anilinosilanes and thence the corresponding anilines in virtually quantitative yields.
Journal ArticleDOI
Cyclizations of N-stannylaminyl radicals onto nitriles.
Luisa Benati,Giorgio Bencivenni,Rino Leardini,Matteo Minozzi,Daniele Nanni,Rosanna Scialpi,Piero Spagnolo,Giuseppe Zanardi,Corrado Rizzoli +8 more
TL;DR: Stannylaminyl radicals derived from radical reactions of Bu(3)SnH with azidoalkylmalonononitriles exhibit highly efficient 5- and 6-exo cyclization onto either nitrile group to give aminoiminyl radicals that in turn are reduced to amidines or undergo successive 5-exe cyclization on an internal alkene.
Journal ArticleDOI
Generation and cyclization of unsaturated carbamoyl radicals derived from S-4-pentynyl carbamothioates under tin-free conditions.
Luisa Benati,Giorgio Bencivenni,Rino Leardini,Matteo Minozzi,Daniele Nanni,Rosanna Scialpi,Piero Spagnolo,Giuseppe Zanardi +7 more
TL;DR: Novel evidence is presented that N-tosyl-substituted carbamoyl radicals display a peculiar tendency to yield the corresponding isocyanate by beta-elimination of the tosyl radical.
