The use of [Co(H)(PMe3)4] as a cobalt catalyst allowed the previously unattainable catalytic version of the cobalt-mediated cycloaddition of triynes and enediynes without the requirement for thermal or light activation. The importance of a chelating group on the substrate that can selectively direct the reaction pathway from enediynes I [X, Y = O, CH2, (MeOCH2)2C; R1 = H, EtO2C, Ph, 4-F3CC6H4, 4-MeOC6H4; R2 = H, Me] toward the classical polycyclic 1,3-cyclohexadienes II or a new family of bicyclic trienes III [from I (R2 = H)] is also demonstrated. In the experiment, the researchers used many compounds, for example, Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9Computed Properties of C10H14O4).
Diethyl 2-(prop-2-yn-1-yl)malonate (cas: 17920-23-9) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.Computed Properties of C10H14O4
