malonic acid dibutyl ester (cas: 1190-39-2) 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. Esters contain a carbonyl center, which gives rise to 120鎺?C閳ユ弲閳ユ彊 and O閳ユ弲閳ユ彊 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C閳ユ彊閳ユ弲 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.

One-pot synthesis of 5-alkylthio-3H-1,2-dithiole-3-thiones was written by Aimar, Mario L.;Rossi, Rita H.. And the article was included in Tetrahedron Letters in 1996.Application In Synthesis of malonic acid dibutyl ester This article mentions the following:

Dialkyl malonate esters RO2CCHR1CO2R (R = Et, n-Bu, n-octyl, R1 = H; R = Et, R1 = PhCH2) reacted with P2S5/S8 in boiling xylene and with 2-mercaptobenzothiazole/ZnO as catalyst to yield 5-alkylthio-3H-1,2-dithiole-3-thiones I as major products. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Application In Synthesis of malonic acid dibutyl ester).
