Group 11 metal complexes of the dinucleating triazole appended bisphosphine 1,4-bis(5-(diisopropylphosphaneyl)-1-phenyl-1H-1,2,3-triazol-4-yl)benzene

Abstract

This paper describes the synthesis and the copper(i), silver(i) and gold(i) complexes of a novel large bite angle bisphosphine {(C6H4(PhC2N3)PiPr2)2-p}.

Diverse structural reactivity patterns of a POCOP ligand with coinage metals

“…Due to the presence of 107 Ag and 109 Ag isotopes, 107 Ag–P and 109 Ag–P couplings take place, which resulted in the broadening of the 31 P NMR spectrum. 11,23 Complex 8 crystallises in the monoclinic C 2/ c space group (Fig. 7).…”

Sterically Demanding Novel Triazole Based Tertiary Phosphines: Synthesis, Transition Metal Chemistry and Catalytic Applications

“…Figure 1 depicts a few triazole based systems known in the literature. [19][20][21][22][23][24][25][26][27][28][29][30] Although several triazole-based phosphine ligands [19,21,24,[26][27][28][29][30][31][32][33][34][35][36] are reported, triazoles functionalized with both phosphine and bulky sidearms are rare. As a part of our continued interest in the synthesis and catalytic application of sterically demanding phosphines [27][28][29][30][31]33,36] and also of others, [32,[37][38][39][40][41][42][43] herein we report the synthesis and transition metal chemistry of bulky phosphines 3 and 4 appended with sterically demanding 1,2,3triazole core.…”

The electron-rich bulky monophosphine 4 together with Pd 2 (dba) 3 was found to be an excellent catalyst for Suzuki-Miyaura coupling and amination reactions.…”

1,2,3-Triazole based ligands with phosphine and pyridine functionalities: synthesis, PdIIand PtIIchemistry and catalytic studies

“…7 a , b ,8 We recently reported a series of kinetically favoured as well as thermodynamically preferred triazole-based mono- and bisphosphine ligands through temperature-controlled lithium-halogen/hydrogen exchange reactions and explored their rich transition metal chemistry and catalytic applications. 7 c ,9 Recently, Fossey and coworkers also reported a library of triazole-based mono-phosphines and studied their coordination chemistry and catalytic applications. 10…”

“…Although many triazole-based phosphine ligands are known, 2 h ,9,10,11 triazole systems functionalized with both phosphine and pyridine groups are scarce. Pyridine being more basic than triazole is expected to show interesting coordination modes and find usefulness in catalytic applications.…”
