A Facile Synthesis of Substituted 1,4-Benzothiazepin-5(4H)-ones and Pyrido[3,2-f][1,4]thiazepin-5(4H)-ones − Crystal and Molecular Structure of 2-Ethylthio-4-methyl-5(4H)-oxopyrido[3,2-f][1,4]thiazepine-3-carbonitrile

“…There is some evidence for the existence of compounds like 6 in literature [42] [43] . Furthermore, we were able to isolate the ketene dithioacetal 8 by reaction of 5 with carbon disulfide.…”

EPR Studies on Carboxylic Esters. Part 20. EPR Spectra and Spin Densities in Radical Anions of Isocoumarin, Benzocoumarin and their Sulfur Analogues

“…Thiono-isocoumarin (isochromene-1-thione, 3) was prepared by thionation of 1 with Lawesson's reagent 17,18 in toluene instead of P 4 S 10 . 19,20 Yellow needles, m.p. 106-107 °C (EtOH), lit.…”

“…106-107 °C (EtOH), lit. 19,20 : 106 °C. Dithio-isocoumarin (thioisochromene-1-thione, 4) was prepared by thionation of 2 with Lawesson's reagent 17,18 in toluene instead of P 4 S 10 .…”

Oxidation of 1,3-dihydrobenzo[c]selenaphene (2-selenaindan) to 2,2'-diformyldibenzyldiselenide

“…The organic phase was washed with water (25 ml) and concentrated to give 1.02 g of clear, yellow liquid. Preparation of 2,2-Diformyldibenzyl Diselenide Dimethyl Acetal (10). A solution of 7 (4.0 g, 14.8 mmol) and methanol (100 ml) was ozonolyzed at -60 °C.…”
