New palladium (substituted 1,10-phenanthroline) bis(methoxycarbonyl) complexes [Pd(L–L)(CO2CH3)2]: preparation and structural features

Investigation of the reactivity of palladium(0) complexes with nitroso compounds: relevance to the palladiumphenanthroline-catalysed carbonylation reactions of nitroarenes

“…Recrystallisation from CH 3 OH gave crystals suitable for X-ray analysis. The data are in agreement with those reported in the literature [16]. The organic products were identified and quantified by GC-MS and GC analyses.…”

“…A comparison of our data with those obtained from X-ray powder diffraction [16] shows that there is no significant difference in the geometrical parameters of the molecule obtained with the two techniques. The values are also very close to those of the analogous bonds and angles observed in Pd(2,2%-bipy){C(O)OCH 3 } 2 [15].…”

“…Very recently Romano and co-workers [16] determined the structure of 3 by ab initio X-ray powder diffraction methods. However, we were able to grow crystals of this material suitable for X-ray diffraction and here we report the single-crystal X-ray structure determination for this compound.…”

Silver‐Catalyzed Intermolecular Amination of CH Groups

“…Substitution in the 2-or 9-position (or both) of phenanthroline prevents formation of dinuclear metal complexes. [12,13] These results, together with our pre- 2 68 [b] 3 57 [b] 4 65 [b] 5 71 [b,c] 6 40 [d] 7 35 [d] 8 33 [d] 9 39 …”

“…Studies of substitution effects on palladium phenanthroline complexes have shown that 2,9-substituted phenanthrolines prevent formation of dinuclear palladium species in the crystalline form, while dinuclear structures are favored with complexes of palladium with unsubstituted phenanthroline. [12,13] Using the intermolecular amination reaction shown in Scheme 1, we probed the activity of silver complexes with different phenanthroline derivatives. None of the complexes with derivatives substituted in the 2-and 9-positions catalyze the CÀH amination reaction.…”
