We report the synthesis of air-stable Pd(i) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are competent precatalysts that can mediate cross-coupling amination reactions between aryl halides with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd-catalyzed cross-coupling transformations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C26H35O2P, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 657408-07-6, in my other articles.

A variety of donor-stabilized cationic complexes of the form [Cp(NPt-Bu3)TiMe(L)][MeB(C6F5)3] and [Cp(NPt-Bu3)TiMe(L)] [B(C6F5)4] (L = Py, 4-EtPy, 4-t-BuPy, NC5H4NMe2, PMe 3, Pn-Bu3, PPh3, P(p-MeC6H 4)3 have been prepared and characterized. Prolonged storage in CH2Cl2 solution resulted in chloride for methyl exchange to afford species of the form [CpTi-(NPt-Bu3)Cl(L)] [B(C6F5)4], [{CpTi(NPt-Bu3)Me} 2(mu-Cl)][B(C6F5)4], and [CpTi(NPt-Bu3)(mu-Cl))2[MeB(C6F 5)3]2. The byproduct salt [(o-MeC 6H4)3PCH2Cl] [B(C6F 5)4] was obtained from reactions employing the sterically demanding donor phosphine P(o-MeC6H4)3, suggesting transient generation of the cation [CpTi(NPt-Bu3) Cl(CH2Cl2)]+. Analogous reactivity was not seen in C6H5Cl, although the species [{CpTi(NPt-Bu 3)Me}2(mu-Me)][B(C6F5) 4] could be formed in this solvent. The isolated zwitterionic complex TiCp(NPt-Bu3)Me(mu-MeB(C6F5)3) readily performs insertion chemistry into the Ti-methyl bonds with diisopropylcarbodiimide and diphenylacetylene substrates to afford the cationic species [CpTi(NPt-Bu3)(Ni-Pr)2CMe)][MeB(C 6F5)3], [TiCp(NPt-Bu3)(PhCCPh(Me))] [MeB(C6F5)3], and [TiCp(NPt-Bu 3)(PhCCPh(Me))(PMe3)][MeB-(C6F 5)3. The implications of this chemistry are considered.

Herein, the one-shot fivefold functionalization of azapentabenzocorannulenes by an iridium-catalyzed fivefold C?H borylation reaction that exhibits excellent regioselectivity is reported. The borylated product can be used as a versatile synthetic intermediate for further derivatization via Suzuki?Miyaura cross-coupling reactions. This fivefold borylation/arylation sequence was employed to synthesize liquid-crystalline azapentabenzocorannulenes with five 3,4,5-trialkoxyphenyl groups, which assemble into 1D hexagonal columnar structures over a wide temperature range. The present method expands the variety and utility of azapentabenzocorannulenes as promising pi-conjugated cores.
