“…In‐depth literature survey indicates that the initial studies on the synthesis of polythioamides are based on the condensation reaction of dithioesters (or didithioesters) with diamines ( Scheme ) . By taking advantage of this approach diverse aliphatic, semi‐aromatic and fully‐aromatic polythioamide derivatives were synthesized.…”

ChemistryBefore moving to the recent advances within the last 5 years in the diverse applications of sulfur chemistry in polymer and Sulfur-Containing PolymersSulfur and its functional groups are major players in an area of exciting research taking place in modern polymer and materials science, both in academia and industry. In fact, manifold sulfur-based reactions that are both exceptionally versatile as well as tremendously useful have been implemented, and further utilized for the design and preparation of polymeric materials that lead to a plethora of applications ranging from medicine to optics and nanotechnology to separation science. Hence, within this review, an overview of strategies and developments used over the last 5 years to reinforce the importance of the sulfur functional group in modern polymer and materials science is presented. In particular, many important references in the primary literature of sulfur chemistry are referred to, including thiol-ene, thiol-yne, thiol-Michael addition, disulfide cross-linking, and thiol-disulfide exchange, among others, by explaining and illustrating the important principles. Last but not least, the grand aim to underpin the importance of sulfur in modern polymer and materials science is achieved by presenting selected examples in diverse fields and postulating the respective potential for real-world applications. he is now a full professor at KIT.sulfur atoms, and tetraphenylethene-bearing di(alkyl bromide) (Scheme 3).

“…We have previously synthesized several bis(dithioester)s to prepare poly(thioamide)s through a room-temperature condensation reaction with diamines. [51][52][53] For such a purpose, these bis(dithioester)s need to be obtained in a high purity grade, preferentially in a crystalline form, so we have often preferred long chain alkyl or carboxymethyl bis(dithioester)s.…”

“…The first bis(dithioester)s 52 were prepared from dinitriles using a modification of the method of Marvel et al 54 The first step consists of the addition of a thiol on the nitrile triple bond, the presence of anhydrous hydrogen chloride being required to complete the formation of the imidoester as an imidium salt (Figure 5). Improvements lie in the use of anhydrous conditions and eventually of insoluble polymeric pyridine (cross-linked polyvinylpyridine) instead of pyridine for the second step (sulfhydrolysis of the imidium salt).…”

Thioacylation is a new way for protein chemical modification. Carboxylic dithioesters and -acids react selectively and rapidly at room temperature with aliphatic amines such as lysine epsilon-amino groups leading to thioamide formation, without any other reagent or catalyst. Various thioacylating reagents were synthesized: monofunctional dithioesters bearing on the acylating end various chemical groups such as: aliphatic chains, phenyl group, mono- and dicarboxylic acids, dialkylphosphonic ester, phosphonic acid, thiol, phenol, or quaternary ammonium group. Bifunctional dithioesters containing either a polymethylene chain or an ethylene oxide oligomer as spacer group as well as some mono- and bis(dithio acids) are described. Applications of thioacylation may be involved either in enzyme chemical modifications or in the obtention of new materials from proteins. Bifunctional reagents might be used as cross-linking or coupling reagents.

[1][2][3][4][5][6][7][8][9][10] Levesque et al have prepared nates with aromatic hydrocarbons. However, the many aliphatic polythioamides from bis(dithiocorresponding anilide was obtained in low yield.…”

Thioamide groups were introduced into polystyrenes by the Friedel–Crafts reaction, with phenyl isothiocyanate in nitromethane solution, in the presence of anhydrous aluminium chloride. Free radical copolymerization of 4‐vinyl dithiobenzoate with styrene followed by low‐temperature solution condensation reactions, with excess of amines in N,N‐dimethylformamide, offered another synthetic route to (co)polymers containing thioamine groups in the side chains without crosslinking. © 1998 John Wiley & Sons, Inc.
