Abstract Extending Moore’s law by augmenting complementary-metal-oxide semiconductor (CMOS) transistors with emerging nanotechnologies (X) has become increasingly important. One important class of problems involve sampling-based Monte Carlo algorithms used in probabilistic machine learning, optimization, and quantum simulation. Here, we combine stochastic magnetic tunnel junction (sMTJ)-based bits (p-bits) Field Programmable Gate Arrays (FPGA) to create an energy-efficient CMOS + X (X =...

Abstract Aryl halides are one of the most important chemical feedstocks in pharmaceuticals due to its easy accessibility, inexpensiveness, and widely utilized as aryl radical precursors organic synthetic chemistry. Conventionally, stoichiometric reagents such AIBN/n‐Bu 3 SnH were used for generation from halides, suffered requirement toxic initiators, high temperature thus, development simple, mild strategies highly desirable. Recently, visible light mediated received considerable attention,...

Abstract Here in, we describe the photochemical decarboxylative alkylation of quinoxalin‐2(1 H )‐ones using commercially accessible carboxylic acids with oxygen as sole oxidant through energy transfer process. The coupling diverse array alkyl (1° to 3°) and bioactive is successfully accomplished achieve desired alkylated products.

Abstract Herein, a direct C‐2 alkylation of Heterocyclic‐ N ‐oxides with alkyl amines as Katritzky salts via visible‐light induced deaminative approach was developed. Mechanistic studies revealed that and base were involved to generate an EDA complex, which underwent intermolecular single electron transfer ( SET ) give radical intermediate. Finally, the intermediate further underwent‐addition heterocyclic‐ ‐oxide substrates access desired products 63–94% yield. The method worked well...

Visible light-induced C-3 arylation of quinoxalin-2(1H)-ones with abundantly available aryl iodides good yields via an EDA-complex formation has been accomplished. Both aryl/heteroaryl and possessing electron-donating as well electron-withdrawing groups were coupled to access the desired products in yields. The radical scavenging, EPR, UV-visible experiments, quantum yield revealed that reaction went through a pathway SET process. Furthermore, protocol could also be applied for late-stage...
