, p. 569 - 573 (2007)
The thermosensitive [60]fullerene end-capped poly(N-isopropylacrylamide) was successfully synthesized by the reaction of C60 with dithiobenzoate-terminated poly(N-isopropylacrylamide), which was prepared by reversible addition-fragmentation cha

A facile one pot strategy for the preparation of linear and hyperbranched polyacrylates has been successfully developed by the combination of in situ esterification of acrylic acid with halogenated compounds promoted by 1,1,3,3-tetramethylguanidine (TMG) and RAFT polymerization.

Thermosensitive Gold Nanoparticles
Zhu, Ming-Qiang,Wang, Li-Qiong,Exarhos, Gregory J.,Li, Alexander D. Q.
, p. 2656 - 2657 (2004)
Thermosensitive gold nanoparticles were fabricated by conjugating Au with a thiol-terminated poly(N-isopropylacrylamide) or PPA; this polymer stabilizer exhibits a temperature transition while undergoing a hydrophilic to hydrophobic transformation. The introduction of PPA onto gold nanoparticles has sensitized Au nanoparticles with unique temperature dependence. At low temperature (25 °C), the solutions containing PPA-functionalized gold nanoparticles are transparent, whereas higher temperatures (30 °C) lead to opaque suspensions. The thermosensitive property of PPA-functionalized Au nanoparticles is reversible, and the clear?opaque suspensions can be repeated many times. Copyright

Ynamide-Mediated Thionoester and Dithioester Syntheses

A novel ynamide-mediated synthesis of thionoesters and dithioesters is described. The selective addition reactions of various monothiocarboxylic acids with ynamide furnish α-thioacyloxyenamides, which undergo transesterification with nucleophilic -OH or -SH species to afford thionoesters and dithioesters, respectively. The broad substrate scope, mild reaction conditions, and excellent yields make this method an attractive synthetic approach to thionoesters and dithioesters.
Regioselective reaction of fluorinated aryllithium reagents and carbon disulfide in cyclopentyl methyl ether: Efficient synthesis of dithioesters and liquid crystal compounds having a difluoromethyleneoxy moiety
Araki, Keisuke,Fuchigami, Tsugumichi,Gotoh, Yasuyuki,Inoue, Munenori,Maebayashi, Haruki
, (2020/03/25)
Regioselective reaction (carbophilic over thiophilic attack) of several (o-fluorophenyl)lithium reagents with carbon disulfide was achieved to furnish dithioesters in good yields after alkylation, which are useful precursors of liquid crystal compounds having a difluoromethyleneoxy (-CF2O-) group. Running the reaction in the presence of a copper(I) salt catalyst and cyclopentyl methyl ether as a solvent is optimal.
Investigations of the Thermal Responsiveness of 1,4,2-Oxathiazoles
Hewitt, Russell J.,Ong, Michelle Jui Hsien,Lim, Yi Wee,Burkett, Brendan A.
, p. 6687 - 6700 (2015/10/29)
The first systematic study of the thermal rearrangement/fragmentation of 5,5-disubstituted 1,4,2-oxathiazoles into isothiocyanates is reported. Structure-activity relationships reveal that the choice of substituent at the 5-position of the 1,4,2-oxathiazoles is the predominant factor to influence the ease of fragmentation.
Copper-catalyzed cross-coupling of thiols, alcohols, and oxygen for the synthesis of esters
Lim, Seungyeon,Ji, Miran,Wang, Xi,Lee, Chan,Jang, Hye-Young
supporting information, p. 591 - 595 (2015/01/30)
Copper-catalyzed, one-pot, three-component coupling reactions using thiols, alcohols, and oxygen to form a variety of esters in good yields were studied. In the presence of easily oxidized benzylic and allylic alcohols, thiols were selectively oxidized to form thionoesters, which underwent facile S/O exchange to afford esters. Thiols may be used as an alternative benzoyl source under mild aerobic conditions.
