TL;DR: Racemic 2, 2'-bis(diphenylphosphino)-l, 1'-binaphthyl has been synthesized from 2 2, 2'-dihydroxy-l, l'-biosphine in two steps and resolved into optically pure (R)-(+) and (S) (-) enantiomers by the use of (+)-di-μ-chlorobis[(S)-N,N-dimethyl-α-phenylethylamine-2C,N]dipalladium.

TL;DR: In this paper, the authors present des catalyseurs actifs de la migration d'hydrogene dans les allylamines secondaires et tertiaires pour donner les (E)-enamines et imines correspondants.
Abstract: Utilisation de complexes de Rh(I) du type [Rh(diphosphine) (diene)]ClO 4 et [Rh(diphosphine)(S) 4 ]ClO 4 (diphosphine: diphosphine tertiaire chelatant-cis; diene=cyclooctadiene ou norbornadiene; S=solvant). Ces composes sont des catalyseurs actifs de la migration d'hydrogene dans les allylamines secondaires et tertiaires pour donner les (E)-enamines et imines correspondants

TL;DR: The interaction between the two nonconjugated π-bonds in 1, 4-cyclohexadiene, norbornadiene and bicyclo[2.2]octadiene has been determined by photoelectron spectroscopy to be 1.0, 0.85 and 0.6 eV respectively as mentioned in this paper.

TL;DR: In this paper, it was shown that the rigidly chelating ar-BIAN ligands have an activating effect on the insertion of CO and alkenes in palladium-carbon bonds as compared to other (bidentate) phosphorus and nitrogen ligands and a stabilizing effect on Pd-acyl and Pdalkyl complexes formed.
Abstract: Facile successive insertion of carbon monoxide and strained alkenes has been observed for both neutral Pd(R)X(Ar-BIAN) and cationic [Pd(R)(MeCN)(Ar-BIAN)]SO 3 CF 3 complexes, i.e., complexes containing the rigid bidentate nitrogen ligands bis(arylimino)acenaphthene (Ar-BIAN; Ar=p-MeOC 6 H 4 (p-An), p-MeC 6 H 4 (p-Tol), o,o'-i-Pr 2 C 6 H 3 ), leading to the formation of new multiple insertion products of the type Pd{CH(R'CH(R')C(O)CH(R')CH(R')C(O0)R}X(Ar-BIAN). It appears that the rigidly chelating Ar-BIAN ligands have an activating effect on the insertion of CO and alkenes in palladium-carbon bonds as compared to other (bidentate) phosphorus and nitrogen ligands and a stabilizing effect on the Pd-acyl and Pd-alkyl complexes formed
