Cu-Catalyzed P–C bond formation/cleavage: straightforward synthesis/ring-expansion of strained cyclic phosphoniums

Abstract

Upon reaction with copper(I), peri-halo naphthyl phosphines readily form peri-bridged naphthyl phosphonium salts. The reaction works with alkyl, aryl and amino substituents at phosphorus, with iodine, bromine and chlorine as...

(P,C)-cyclometalated complexes derived from naphthyl phosphines: versatile and powerful tools in organometallic chemistry

“…Finally, efficient catalytic conditions were established to obtain peri -bridged naphthyl-phosphonium using only 1–5 mol% of copper( i ) starting from peri iodo- or bromo-naphthyl phosphines (Scheme 19). 38…”

“…Finally, efficient catalytic conditions were established to obtain peri-bridged naphthyl-phosphonium using only 1-5 mol% of copper(I) starting from peri iodo-or bromo-naphthyl phosphines (Scheme 19). 38 Scheme 16 Phosphorus peri-bridged naphthalene derivatives and their ring expansion into (P,C)-cyclometalated naphthyl complexes by oxidative addition to Pt and Pd.…”

Mechanochemical Nickel‐Catalyzed Carbon‐Sulfur Bond Formation between Aryl Iodides and Aromatic Sulfur Surrogates

“…Previously, we mainly focused on the direct solid-state synthesis of coordination complexes by dehydrohalogenation of hydrogen-bonded halometallate salts and then used as the non-noble metal catalyst to implement CÀ S coupling. [26,27] According to the literature, [28] group 10 metals, particularly palladium, and nickel, occupy the forefront positions in chemical reactions. Of these, the unusual properties of nickel have piqued the interest of chemists.…”

Platinum Assisted Tandem P–C Bond Cleavage and P–N Bond Formation in Amide Functionalized Bisphosphine o-Ph2PC6H4C(O)N(H)C6H4PPh2-o: Synthesis, Mechanistic, and Catalytic Studies

“…The phosphorus-containing π-conjugated molecules show potential applications as fluorescent dyes for bioimaging and organic light-emitting diodes (OLEDs). − For instance, the synthesis of phosphacycles including dibenzophosphole by Pd­(II)-mediated P–C bond metathesis has been documented. , However, the bulk of research on the P–C bond metathesis (P–C/X exchange) involved palladium complexes, ,,,, whereas the studies on the utility of other metals are scant. − Recently, Youichi and co-workers reported the synthesis of Ru II -based five- and six-membered phosphacycles through reductive elimination of phosphonium salt . Similarly, Toste and co-workers investigated the reductive elimination of phosphonium at the Au III center .…”
