Usage

General Description

Benzenemethanol, 4-(2-propenyloxy)-, also known as estragole, is an organic compound and a naturally occurring aromatic ingredient commonly found in essential oils such, tarragon, basil, fennel, anise, and star anise. Estragole has a sweet, aromatic odor and is often used as a flavoring agent in food and beverages. It is also used in the production of perfumes and fragrances. However, there is some controversy surrounding the safety of estragole, as high doses have been linked to potential carcinogenic effects in animals, leading to restrictions on its use in the food and fragrance industries. Regulatory agencies, such as the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), have set limits on the amount of estragole that can be used in consumer products.

Homologation of Electron-Rich Benzyl Bromide Derivatives via Diazo C-C Bond Insertion

The ability to manipulate C-C bonds for selective chemical transformations is challenging and represents a growing area of research. Here, we report a formal insertion of diazo compounds into the "unactivated"C-C bond of benzyl bromide derivatives catalyzed by a simple Lewis acid. The homologation reaction proceeds via the intermediacy of a phenonium ion, and the products contain benzylic quaternary centers and an alkyl bromide amenable to further derivatization. Computational analysis provides critical insight into the reaction mechanism, in particular the key selectivity-determining step.

GaN nanowires as a reusable photoredox catalyst for radical coupling of carbonyl under blacklight irradiation

Employing photo-energy to drive the desired chemical transformation has been a long pursued subject. The development of homogeneous photoredox catalysts in radical coupling reactions has been truly phenomenal, however, with apparent disadvantages such as the difficulty in separating the catalyst and the frequent requirement of scarce noble metals. We therefore envisioned the use of a hyper-stable III-V photosensitizing semiconductor with a tunable Fermi level and energy band as a readily isolable and recyclable heterogeneous photoredox catalyst for radical coupling reactions. Using the carbonyl coupling reaction as a proof-of-concept, herein, we report a photo-pinacol coupling reaction catalyzed by GaN nanowires under ambient light at room temperature with methanol as a solvent and sacrificial reagent. By simply tuning the dopant, the GaN nanowire shows significantly enhanced electronic properties. The catalyst showed excellent stability, reusability and functional tolerance. All reactions could be accomplished with a single piece of nanowire on Si-wafer. This journal is
