Isopropylisothiocyanate (cas: 2253-73-8) 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. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C4H7NS

Regioselective (thio)carbamoylation of 2,7-di-tert-butylpyrene at the 1-position with iso(thio)cyanates was written by Wrona-Piotrowicz, Anna;Witalewska, Marzena;Zakrzewski, Janusz;Makal, Anna. And the article was included in Beilstein Journal of Organic Chemistry in 2017.Formula: C4H7NS The following contents are mentioned in the article:

It has been found that 2,7-di-tert-butylpyrene reacts with aliphatic iso(thio)cyanates X=C=NR (R = Et, Bu, cyclohexyl, etc.) in the presence of trifluoromethanesulfonic acid to exclusively afford the corresponding 1-substituted (thio)amides I (R1 = H, C(O)NHC6H5, C(S)NHC6H5, C(S)NHCH2C6H5, 4-CH3OC6H4NHC(O); R2 = H; X = O, S) in high yields. For aromatic iso(thio)cyanates X=C=NR (R = Ph, benzyl and 4-methoxyphenyl) the reaction is less regioselective, although substitution at the 1-position prevails. For ethoxycarbonyl isothiocyanate, apart from the 1-substituted thioamide I (R = C(O)OC2H5; R1 = H; R2 = H; X = S), 1,8-disubstituted thioamide I (R = C(O)OC2H5; R1 = H; R2 = C(S)NHC(O)OC2H5; X = S) and 2,7-di-tert-butylpyrene-1-carbonitrile are formed (especially at longer reaction times). This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Formula: C4H7NS).
