“…Thus, one can suggest that the introduction of CO in the trans-position occurs at a higher rate and is determined by the nature of an acid used. The effect of the nature of the acid on the cis-and transposition of olefin group was observed also in reactions of β-elimination, when halogen acids bring about the formation of trans-olefins, while arylsulfonic acid gives cis-olefins [22]. We believe that this fact can be explained by the steric hindrances arising from the acid molecule dimensions.…”

Pd complexes of (RR)- and (SS)-1,5-methylbenzyl-3,7-diphenyl-1,5-diaza-3,7-diphosphacyclooctane as catalysts in alternating cooligomerization of CO with dienes

Alternating copolymerization of CO with norbornadiene and ethylidenenorbornene is studied in the presence of Pd complex with ( SS )-1,5-methylbenzyl-3,7-diphenyl-1,5-diaza-3,7-diphosphacyclooctane ligand. The structure of cooligomers formed and cooligomerization rate are shown to depend on the catalytic system composition and comonomer structure. The obtained cooligomers are characterized by structural methods.

“…They were included in the refinement in the ridingmodel approximation, with isotropic displacement parameters set to 1.2U eq of the carrier atom (1.5U eq for CH 3 and NH 3 H atoms). In the absence of significant anomalous scattering, Friedel pairs were merged prior to the final refinement; the absolute configuration is known from the synthesis (Carey & Sundberg, 1984).…”

In the title compound, C7H13NO4, there are two independent molecules in the asymmetric unit. All bond lengths and angles in the molecules are in normal ranges. The ψ1 and ψ2 torsion angles are 159.9 (4) and −23.4 (5)°, respectively, in the first molecule, and the ψ3 and ψ4 torsion angles 157.7 (4) and −26.7 (5)°, respectively, in the second. Each of the independent molecules has a different comformation. The translationally and screw‐related molecules are connected by N—H⋯O hydrogen bonds, forming a two‐dimensional network parallel to the ac plane.

“…For example, the rate constants for the oxidation of methyl cinnamate with methyltri-n-octylammonium permanganate are greater than that with tetra-n-octylammonium permanganate because the former allows a greater penetration of the anion into the structure of the cation [12,15,16]. It therefore appears that QAPs may exist as solvent-separated ion pairs in acetone, but as intimate ion pairs in toluene and methylene chloride [17][18][19].…”
