Singly occupied molecular orbital (SOMO) activation provides a pathway for asymmetric a-addition to aldehydes. The scope of SOMO activation includes the allylation, enolation, vinylation, styrenation, chlorination, polyene cyclization, and arylation of a range of aldehydes. This union of organocatalysis with single-electron oxidative coupling is an intricate process involving the complex balanc...
Organo-fluorine compounds are the substances of considerable interest in various industrial fields due to their unique physical and chemical properties. Despite increased demand in wide fields of science, synthesis of fluoro-organic compounds is still often faced with problems such as the difficulties in handling of fluorinating reagents and in controlling of chemical reactions. Recently, flow ...
INTRODUCTION Industrial nitrogen fixation plays an important role in sustaining approximately 40% of the Earth’s population through generation of synthetic fertilizers. Annually, ca. 500 million tons of anhydrous ammonia, ammonium nitrate, and urea are produced through the Haber-Bosch process, which requires harsh conditions (200 atm, 450-500C) and affords low yields 10-20%. It has been estimat...
Microbial necromass is a large, dynamic and persistent component of soil organic carbon, the dominant terrestrial carbon pool. Quantification stocks its susceptibility to global change becoming standard practice in research. However, typical proxies used for do not reveal nature flows transformations within that ultimately determine persistence. In this review, we define deconstruct four stages...
