, p. 13595 - 13603 (2018)
A novel phototriggered functionalization reaction of a carboxylic acid using an aminocyclopropenone has been developed. Irradiation of an aminocyclopropenone and carboxylic acid mixture generated ketones that possessed substituents from both the carboxylic acid and the aminocyclopropenone. This reaction occurred through two distinct phototriggered processes. Using this reaction, substituents in an aminocyclopropenone can be connected with a carboxylic acid containing molecule.

A phototriggered dehydration condensation using an aminocyclopropenone has been developed. The UV irradiation of an aminocyclopropenone generated a highly reactive ynamine in situ and the dehydration condensation of a carboxylic acid and an amine coexisting in the reaction solution smoothly proceeded to afford an amide. This reaction is completely controllable by the ON/OFF states of a UV lamp.

We have described an efficient method for oxidative cross coupling reactions between activated N-H amines and terminal alkynes using heterogeneous Cu2(BDC)2(BPY) as recyclable catalyst (BDC = benzene-1,4-dicarboxylate; BPY = 4,4′-bipyridine). The optimal conditions involved the use of inexpensive NaHCO3 base and oxygen as terminal oxidant in toluene solvent at 80°C. Reactions proceeds efficiently, and high selectivity with only trace amount of diynes as well as good yields were achieved in a short reaction time. The Cu2(BDC)2(BPY) exhibited excellent catalytic activity and selectivity as compared to other Cu-MOFs on a broad reaction scope. Interestingly, the presence of bipyridine ligand was shown to enhance the catalyst stability. Thus, the Cu2(BDC)2(BPY) could be facilely separated from the reaction mixture by simple centrifugation and could be reused several times with only a slight decrease in catalytic activity.
Reactions of N-(1-Alkinyl)anilines with Sulfonylacetylenes

The N-(1-alkinyl)anilines 8 react with sulfonylacetylenes 9 to give the 2-anilino-5-sulfinylfurans 10.The possible mechanism of this reaction, which is similar to the Pummerer reaction, is discussed.
