1,6-Heptadiynes disubstituted at position 4 by acetyl, ethoxycarbonyl, and nitrile groups was written by Plouin, Dominque;Glenat, Rene. And the article was included in Comptes Rendus des Seances de l’Academie des Sciences, Serie C: Sciences Chimiques in 1972.Recommanded Product: Diethyl 2-(prop-2-yn-1-yl)malonate This article mentions the following:
The title compounds, RR1C(CH2C顚咰H)2 (I), were prepared in 84-92% yields by condensing HC顚咰CH2Br with CH2RR1 in K2CO3-Me2CO. The formation of minor products, substituted furans, and MeCOCH(CH2C顚咰H)2, was discussed. Four I (R = COMe, CO2Et; R1 = COMe, CO2Et, CN) were prepared In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Recommanded Product: Diethyl 2-(prop-2-yn-1-yl)malonate).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Recommanded Product: Diethyl 2-(prop-2-yn-1-yl)malonate
