On November 19, 2021, Gallo, Rafael D. C.; Duarte, Marcelo; da Silva, Amanda F.; Okada, Celso Y. Jr.; Deflon, Victor M.; Jurberg, Igor D. published an article.Product Details of 872046-08-7 The title of the article was A Selective C-C Bond Cleavage Strategy Promoted by Visible Light. And the article contained the following:
A new visible-light-promoted reaction between aryldiazoacetates ArC(=N2)COOR1 (Ar = Ph, 4-chlorophenyl, 3,5-dimethoxypheny, etc.; R1 = Me, Bn, i-Pr, allyl) and 1,3-diketones R2C(O)CH2C(O)R3 (R2 = Me, 4-chlorophenyl, cyclopropyl, etc.; R3 = Me, Ph, 2-methoxyphenyl, etc.) allows good yields and selectivities for C-C bond insertions, leading to the corresponding 1,4-dicarbonyl compounds R2C(O)C(COOR1)(Ar)CH2C(O)R3 . This transformation is straightforward and highly practical. It tolerates air and moisture and does not require the use of any metals. Mechanistic investigations support the involvement of a key cyclopropanol intermediate derived from an intramol. rearrangement. The experimental process involved the reaction of Methyl 2-(2,6-difluorophenyl)acetate(cas: 872046-08-7).Product Details of 872046-08-7
