Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Formula: C8H16O2

Pd-catalyzed alkoxycarbonylation of alkenes promoted by H2O free of auxiliary acid additive was written by Liang, Wen-Yu;Liu, Lei;Zhou, Qing;Yang, Da;Lu, Yong;Liu, Ye. And the article was included in Molecular Catalysis in 2020.Formula: C8H16O2 The following contents are mentioned in the article:

The Pd-catalyzed and water promoted alkoxycarbonylation of alkenes using alcs. and carbon monoxide to afford esters RCHR1C(O)OR2 [R = n-Bu, cyclohexyl, Ph, etc.; R1 = H, Me; R2 = Me, Et, iPr] was reported. Water instead of Bronsted/Lewis acid was found to effectively improve the catalytic performance of Pd(MeCN)2Cl2-Xantphos system for alkoxycarbonylation of alkenes. Under the optimal conditions, the best yield of 97% was obtained for the target products Me 3-phenylpropanoate and Me 2-phenylpropanoate with L/B of 4.3 and TON of 192. The in situ high pressure FT-IR anal. verified that water played an important role in promoting formation and stability of Pd-H active species which was responsible for the efficient alkoxycarbonylation of alkenes. In addition, the ligand effect of Xantphos on this reaction was discussed. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Formula: C8H16O2).
