A metal- and additive-free ipso-benzylation of arylsilanes was developed to efficiently synthesize symmetrical and unsymmetrical diarylmethanes.
Established herein is a Rh(III)-catalyzed direct ortho-C–H diarylation of arylsulfoximine derivatives with diverse environmentally friendly arylsilanes, allowing the synthesis of potentially valuable tricyclic arylsulfoximine derivatives.
A multiligand-involved Cu catalysis offers an efficient Hiyama coupling of arylsilanes with unactivated alkyl halides, where copper with NHC and phenanthroline ligands were account for C(sp2)–Si activation and C(sp2)–C(sp3) formation, respectively.
Silylation of arylbromides with (Me3Si)3SiH via dual photoredox Ni-catalysis enables the preparation of arylsilanes at room temperature under visible-light irradiation.
In this comprehensive review, we present a systematic analysis of C(sp2)–C(sp2) bond formation via iron-catalysed coupling reactions as documented in the extant literature.
