4973-29-9 Usage

General Description

4-Phenoxy Styrene is a clear to slightly yellow liquid with a faint odor. It is a chemical compound primarily used in the production of polymers, resins, and other industrial materials. It is a styrene derivative and can be polymerized to form various types of plastics. 4-Phenoxy Styrene is also used as a chemical intermediate in the production of specialty chemicals, pharmaceuticals, and agricultural products. It is a flammable substance with potential health hazards if not handled properly, and it should be stored and used with caution in industrial settings.

Check Digit Verification of cas no

The CAS Registry Mumber 4973-29-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4973-29:
(6*4)+(5*9)+(4*7)+(3*3)+(2*2)+(1*9)=119
119 % 10 = 9
So 4973-29-9 is a valid CAS Registry Number.

Site-Selective Acceptorless Dehydrogenation of Aliphatics Enabled by Organophotoredox/Cobalt Dual Catalysis

Zhou, Min-Jie,Zhang, Lei,Liu, Guixia,Xu, Chen,Huang, Zheng

supporting information, p. 16470 - 16485 (2021/10/20)

The value of catalytic dehydrogenation of aliphatics (CDA) in organic synthesis has remained largely underexplored. Known homogeneous CDA systems often require the use of sacrificial hydrogen acceptors (or oxidants), precious metal catalysts, and harsh reaction conditions, thus limiting most existing methods to dehydrogenation of non- or low-functionalized alkanes. Here we describe a visible-light-driven, dual-catalyst system consisting of inexpensive organophotoredox and base-metal catalysts for room-temperature, acceptorless-CDA (Al-CDA). Initiated by photoexited 2-chloroanthraquinone, the process involves H atom transfer (HAT) of aliphatics to form alkyl radicals, which then react with cobaloxime to produce olefins and H2. This operationally simple method enables direct dehydrogenation of readily available chemical feedstocks to diversely functionalized olefins. For example, we demonstrate, for the first time, the oxidant-free desaturation of thioethers and amides to alkenyl sulfides and enamides, respectively. Moreover, the system's exceptional site selectivity and functional group tolerance are illustrated by late-stage dehydrogenation and synthesis of 14 biologically relevant molecules and pharmaceutical ingredients. Mechanistic studies have revealed a dual HAT process and provided insights into the origin of reactivity and site selectivity.

Regioselective Copper-Catalyzed Boracarboxylation of Vinyl Arenes

Butcher, Trevor W.,McClain, Edward J.,Hamilton, Tyler G.,Perrone, Trina M.,Kroner, Kayla M.,Donohoe, Gregory C.,Akhmedov, Novruz G.,Petersen, Jeffrey L.,Popp, Brian V.

, p. 6428 - 6431 (2016/12/23)

Regioselective copper-catalyzed boracarboxylation of vinyl arenes with bis(pinacolato)diboron and carbon dioxide has been achieved. New boron-functionalized α-aryl carboxylic acids, including nonsteroidal anti-inflammatory drugs (NSAIDs), are obtained in moderate to excellent yields. The synthetic utility of the transformation was shown through subsequent derivatization of the carbon-boron bond yielding formal hydroxy- and fluorocarboxylation products as well as anionic difluoroboralactones.
