Zur Kenntnis der Trithiokohlensäure. IV. Über die Herstellung und Eigenschaften von Trithiokohlensäure‐di‐estern und ihre Verwendbarkeit als Schädlingsbekämpfungsmittel

Abstract

Trithiokohlensäure‐di‐ester der aliphatischen, araliphatischen und aromatischen Reihen wurden hergestellt und ihre chemischen sowie biologischen Eigenschaften untersucht. Das leicht zugängliche Barium‐trithiocarbonat hat sich bei der Herstellung von aliphatischen und araliphatischen Estern bewährt. Von den untersuchten Estern zeigten lediglich die Diaryl‐trithio‐carbonate günstige insektizide Wirkung.

Model studies related to the cofactor of oxomolybdoenzymes. Part 3

“…The acetal unit in ( 16) could be readily hydrolysed producing the corresponding diol (19) which can be seen to be a direct analogue to the pteridine degradation product (20) of M o c o . ~~ Further, we suggest that a route, via intermediates such as (17) and ( 18), to a thienoquinoxaline may well parallel in part that by which the Moco degradation product ( 20) is produced.…”

“…The ether extract was dried and evaporated under reduced pressure to give a pale brown gum purification of which by column chromatography, eluting with dichloromethane-ethyl acetate, gave first the ditosyfute (3b) (0.41 g, 40%), as a crystalline solid, m.p. 159-161 "C (from dichloromethane-hexane); 6 , 8.67 ( (19), and 173 (15) (Found: C, 59.2; H, 5.4; N, 6.3; S, 7.1. C22H24N206S requires C, 59.5; H, 5.5; N, 6.3; S, 7.2%).…”

Atom economical synthesis of di- and trithiocarbonates by the lithium tert-butoxide catalyzed addition of carbon disulfide to epoxides and thiiranes

“…36,37 Cyclic thiocarbonates have attracted much attention due to their wide range of applications. 44 On the other hand trithiocarbonates 4 exhibit radioprotective, 40 insecticidal and fungicidal 45 activities. 40 In general, thiocarbonates can be used in the synthesis of olefins 41 and deoxygenation reactions of alcohols 42 as well as ligands for metal cations 43 and RAFT-polymerization reagents.…”

Titanium(salen)‐Catalysed Synthesis of Di‐ and Trithiocarbonates from Epoxides and Carbon Disulfide

“…Dithiocarbonates 3 and trithiocarbonates 4 have been shown to possess radioprotective activity 11. Dithiocarbonates have also been used in polymer syntheses,12, 13 and trithiocarbonates have been found to possess insecticidal activity 14. However, the chemistry shown in Scheme often requires harsh reaction conditions (high temperatures and pressures), even in the presence of a suitable catalyst 1–6…”
