Herein, authors report on the photocatalytic reaction of acceptor/acceptor diazoalkanes with terminal alkynes. Exptl. and computational studies suggest the formation of a key triplet carbene intermediate that underwent an addition reaction to the alkyne followed by cyclization to give furan heterocycles (31 to 90% yield). This reaction was studied with a broad range of alkynes and acceptor/acceptor diazoalkanes and now provides access to furans under mild reaction conditions. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3Electric Literature of C6H9ClO3).
Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Electric Literature of C6H9ClO3
