Abstract: The FeIII(phen)3 catalysis of the benzylic C(sp3)-H azidation of indoles has been investigated. The Fe(III) complex can selectively oxidize indoles to form arene radical cations, which are transformed into benzylic C(sp3) radical intermediates. This strategy… read more here.

Abstract: Single-electron oxidation and α-deprotonation of tertiary anilines using Fe(phen)3(PF6)3 afford α-aminoalkyl radicals, which can be coupled with electrophilic partners to afford various tetrahydroquinolines. Mechanistically, the Fe(phen)n2+/3+ catalytic cycle is maintained by O2 or a TBHP… read more here.

Abstract: Alkynylsilanes are one kind of essential synthetic block in organic chemistry. The established synthetic routes retain some drawbacks regarding harsh reaction conditions or expensive/rare metal catalysts. Herein, we report a method for iron-catalyzed, visible-light-induced alkynylation… read more here.
