Application of 1403850-00-9On September 18, 2020 ,《Development of Bronsted Base-Photocatalyst Hybrid Systems for Highly Efficient C-C Bond Formation Reactions of Malonates with Styrenes》 was published in ACS Catalysis. The article was written by Bas, Sebastian; Yamashita, Yasuhiro; Kobayashi, Shu. The article contains the following contents:
Bronsted base-photocatalyst hybrid systems were developed for reactions of malonates with styrene derivatives to afford dialkyl-((aryl)alkyl)malonates (R1)(Ar)CHCH(R2)CH(CO2R3) [R1 = H, Me, Ph, etc.; R2 = H, Me, Ph; R3 = Me, Et, i-Pr, etc.; Ar = Ph, 4-MeC6H4, 2-pyridyl, etc.]. The concept of this process lies in the photooxidation of catalytic amounts of the enolate to form reactive radicals that react with alkene double bonds under mild reaction conditions. This was an example of visible light activated C-C bond formation reactions of malonates with alkenes to realize high atom economy under very mild reaction conditions without using any transition metal catalysts. The experimental part of the paper was very detailed, including the reaction process of 2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile(cas: 1403850-00-9Application of 1403850-00-9)
2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile(cas: 1403850-00-9) is cyanoarene-based donor-acceptor photocatalyst developed by the Zeitler group. While this catalyst has a balanced redox profile, allowing for its use in a variety of transformations, it stands out as the most reducing catalyst of the family.Application of 1403850-00-9
