The stereoselectivity of the Staudinger reactions involving monosubstituted ketenes with electron acceptor substituents was investigated experimentally by determination of the product stereochemistry and theoretically via DFT calculations. The results indicate that imines preferentially attack the less sterically hindered exo-side of the ketenes to generate zwitterionic intermediates. Subsequen...

The research discussed a pressure, opportunity, as well rationalization have positive effect on corruption. However, the system does not weaken influence of rationalization, and ability corruption neither internal control strengthen negative integrity Therefore, SPIP in Supreme Court Republic Indonesia must be able to adapt COSO theory since is government body that specifically characterized la...

Cressey’s [1] fraud triangle examined the motivation for crime. McMahon et al. [2] suggest there is a need to move beyond the traditional fraud triangle to fight white-collar crime. In this article, we suggest a white-crime triangle which includes financial motive, organizational opportunity and deviant behavior. The suggested white-collar crime triangle is based on convenience theory [3], wher...

The development of high-performance transparent conducting oxides is critical to many technologies from transparent electronics to solar cells. Whereas n-type transparent conducting oxides are present in many devices, their p-type counterparts are not largely commercialized, as they exhibit much lower carrier mobilities due to the large hole effective masses of most oxides. Here we conduct a hi...
