structure of the resultant polymers and on the corresponding photovoltaic performance, a comprehensive investigation was conducted on the distinction between two PTB7-Th samples prepared from Stille coupling polymerization with the classic palladium catalysts Pd2(dba)3/P(o-tol)3 and Pd(PPh3)4, ...
Pd (CO) (PPh3)3 could be isolated from the reaction mixture arising from cyclohexene hydrocarboxylation by PdCl2 (PPh3)2 as the catalyst precursor; furthermore, it has also been prepared through direct reaction of Pd (PPh3)4 with CO in benzene. For this complex, 31P- and 13C-NMR. ...
Synthesis, crystal, and molecular structure of the palladium(0)-fullerene derivative (.eta.2-C60)Pd(PPh3)2 Buckminsterfullerene, C60, reacts with Pd-(PPh3)4 in solution to give in high yield a palladium(0) complex, (C60)Pd(PPh3)2, in which fullerene is ligated i... VV Basbilov,PV ...
The first dipalladium μ-PPh3complex (1) was obtained by the facile loss of two CH3CN ligands from [Pd2(PPh3)2(CH3CN)4](PF6)2 in CH2Cl2. Coupling of p-tolylacetylene (p-TolC≡CH) with 1 or its precusor afforded the μ-butenediylidene complex 2, treatment of which with CH3CN resul...
