Electric Literature of C54H45ClP3Rh. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Tris(triphenylphosphine)chlororhodium, is researched, Molecular C54H45ClP3Rh, CAS is 14694-95-2, about Rhodium-Catalyzed PIII-Directed ortho-C-H Borylation of Arylphosphines.

Transition-metal-mediated metalation of an aromatic C-H bond that is adjacent to a tertiary phosphine group in arylphosphines via a four-membered chelate ring was first discovered in 1968. Herein, we overcome a long-standing problem with the ortho C-H activation of arylphosphines in a catalytic fashion. In particular, we developed a rhodium-catalyzed ortho-selective C-H borylation of various com. available arylphosphines with B2pin2 through PIII-chelation-assisted C-H activation. This discovery is suggestive of a generic platform that could enable the late-stage modification of readily accessible arylphosphines.
