The Effect of Property Rights on Entrepreneurship:Evidence from Some Factor-driven, Efficiency-driven, and Innovation-driven Countries

Entrepreneurship is influenced by many factors and environments such as institutions. Institutions have an important role to play in the individual's tendency toward necessity and opportunity entrepreneurship. The purpose of this paper was to examine the impact of institutional quality (property rights) on opportunity and necessity entrepreneurship. The results, based on unbalanced panel data f...

Diphenylphosphinoyl-mediated synthesis of ketones.

alpha-Diphenylphosphinoyl ketones are selectively and sequentially alkylated at the alpha-position. Double lithiation and selective alkylation occurs at the less stabilised gamma-position. Dephosphinoylation of the alkylation products gives ketones. Mono-alkylation is selective, highly crystalline intermediates are formed and a one-pot strategy is possible. The method is ideally suited for the ...

Event-driven and Attribute-driven Robustness

Over five decades have passed since the first wave of robust optimization studies conducted by Soyster and Falk. It is outstanding that real-life applications of robust optimization are still swept aside; there is much more potential for investigating the exact nature of uncertainties to obtain intelligent robust models. For this purpose, in this study, we investigate a more refined description...

Heterotrophic Production of Methyl Ketones

nBu4NI-catalyzed oxidative imidation of ketones with imides: synthesis of α-amino ketones.

nBu4NI-Catalyzed oxidative imidation of ketones and imides for the synthesis of α-amino ketones were realized for the first time. The methodology is characterized by its wide substrate scope even for acetone with readily available phthalimide, saccharin and succinimide, which opens a new pathway for direct imidation of ketones.
