To deal with change, organizations need to find and nurture those who are most facile in dealing with it. Identifying those who can learn to behave in new ways requires a different measurement strategy from those often employed, one that looks at the characteristics of the learning agile. In this article, we explain some initial steps toward identifying the women and men with the most potential to lead, regardless of what the future may hold for them. As indicated by a measure of learning from experience, those with the highest potential tend to be interested in first-time challenges, are eager to learn, and can get results under tough conditions.

and catalytic mono-N-alkylation method of both aromatic and aliphatic amines using nitriles as an alkylating agent with Pd/C or Rh/C as a catalyst is described. This method is particularly attractive to provide an environmentally benign and applicable alkylation method of amines without using toxic and corrosive alkylating agents such as alkyl halides and carbonyl compounds.

A new, general ortho/para-selective anodic dehydrogenative cross-coupling of two aryl amines, naphthalen-2-amine derivatives and anilines, is described. This electrochemical protocol assembles a wide range of unsymmetrical biaryls in good to excellent yields under mild, additional-metal-catalyst-free, oxidant-free conditions with excellent selectivity, broad substrate scope, and wide functional group
Playing Reversi with H and N: A copper‐catalyzed intermolecularregioselectivehydroamination of styrenes with polymethylhydrosiloxane and hydroxylamine derivatives has been developed. The catalysis accommodates challenging β‐substituted substrates. Moreover, the chiral biphosphine‐ligated copper complex successfully forms benzylamines with good enantiomeric ratios.
convenient Pd(0)-catalyzed carboannulation with propargylic compounds for the synthesis of highlysubstituted aromatic amine derivatives in a one-pot operation was developed. In this process, a significant breakthrough in aminobenzannulation is observed. Moreover, the reaction appears to be very general and suitable for a variety of amines.
The first heterogeneously catalyzed oxidative dehydrogenative cross‐coupling of aryl amines is reported herein. 2‐Naphthylamine analogues were reacted with various electron‐rich arenes using a heterogeneous Rh/C catalyst under mild aerobic conditions, thus affording nonsymmetrical biaryl amines in excellent yields with high selectivities. This reaction provides a mild, operationally simple, and efficient
