Reaktionsverhalten alkinyl-substituierter phosphinite und phosphane am beispiel von kupfer(I) - und Silber(I) - trifluormethansulfonaten

From heterobimetallic transition metal complexes to linear coordination polymers based on cis‐ and trans‐L2Pt(CCPh)2

“…Similar orientations were found in, e.g. {[(R 1 )(R 2 )(PhC C)P]Ag(-OSO 2 CF 3 )} 2 (R 1 = OC 6 H 2 t Bu 3 -2,4,6; R 2 = NEt 2 , Ph, PhC C) [30].…”

“…8). One should mention that the formation of such bridging entities is not common in group 11 triflate chemistry [30]. Similar orientations were found in, e.g.…”

Synthesis and characterization of mono- and binuclear platinum complexes containing terminal and bridging diynyldiphenylphosphine ligands

“…Transition metal complexes containing alkynyl phosphines (PPh 2 C≡CR) display a fascinating chemistry and have been widely investigated. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Although diynylphosphine ligands may offer higher coordination possibilities and new reaction paths they have, however, been less explored. The diynylphosphines PPh 2 C≡CXC≡CR are also potential building blocks to build new polymetallic complexes with interesting structural and material properties.…”

“…17,18,20,22 P-C (alkyne) bond activation followed, in some cases, by interesting C-C coupling reactions is much less common but have also been reported. [22][23][24][25] Thus, Carty and co-workers have shown that the thermolysis of Pcoordinated phosphine clusters [Ru 3 (CO) 11 (PPh 2 C≡C-C≡CR)] (R = Bu t , Ph, SiMe 3 ) produces binuclear r-p butadiynyl complexes [Ru 2 (CO) 6 (l-PPh 2 )(l-g 1 ,g 2 -C≡C-C≡CR) and several higher nuclearity clusters containing unusual polyyne ligands resulting from P-C sp bond cleavage followed by useful C-C coupling reactions. [23][24][25] Mixed-metal clusters 18,20, 22 and molecular triangles, 3 have been also recently prepared using bis(phosphinoalkyne) ligands PPh 2 C≡C-X-C≡CPPh 2 .…”

Organometallic π-Tweezers, NCN Pincers, and Ferrocenes as Molecular “Tinkertoys” in the Synthesis of Multiheterometallic Transition-Metal Complexes

“…In 9 , trans -(Ph 3 P) 2 Pt(C⋮CPh) 2 units are linked by [Ag(μ-OCl(O) 2 O)] 2 rings. 16b,, The silver(I) ion is additionally η 2 -coordinated to one phenyl group of a triphenylphosphine ligand to result in a pseudotetrahedral coordination sphere at silver. The structure of 9 is dominated by the parallel orientation of individual Pt(C⋮CPh) 2 units (Figure ).…”
