Studies on Fungicides. XXV. Addition Reaction of Dithiocarbamates to Fumaronitrile, Bis (alkylthio) maleonitrile, 2, 3-Dicyano-5, 6-dihydro-1, 4-dithiin and 4, 5-Dicyano-2-oxo-1, 4-dithiole
摘要:
5-氰甲基-2-硫酮-4-氨基硫氮茂 (II) 可用富马睛与二硫代氨基甲酸盐的加成反应来制备。用二硫代氨基甲酸盐与双 (甲硫基) 马来睛 (IXa),双 (苄硫基) 马来睛 (IXb),2,3-二氰基-5,6-二氢-1,4-二硫茂 (IXc)及4,5-二氰基-2-氧-1,4-二硫茂 (IXd) 反应,制得了 5,5'-双-2-硫酮-4-氨基硫氮茂 (X)。发现 II 及 X 的 4-氨基对酸不稳定,与无机酸加热时,即水解而得 5-氰甲基-2-硫酮-4-硫氮杂茂酮 (III) 及 5,5'-双-2-硫酮-4-硫氮杂茂酮 (XII)。发现 X 于催化量的三乙胺存在时可自动氧化成 Δ 5,5'-双-2-硫酮-4-亚氨基硫氮茂 (XI)。由 N-苄基二硫代氨基甲酸盐与5-亚氰甲基-2-硫酮-4-硫氮杂茂酮 (XIV) 的加成反应制得了 4-氧-4,亚氨基-Δ5,5'-双-2-硫酮-硫氮杂茂酮 (XVI)。用无机酸水解 XI 及 XIV,制得了 Δ5,5'-双-2-硫酮-4-硫氮杂茂酮 (XIII)。

A series of thin-film n-channelorganic field-effect transistors based on various birhodanines, 3,3′-dialkyl-5,5′-bithiazolidinylidene-2,2′-dione-4,4′-dithiones (OS-R) and their sulfur analogues, 3,3′-dialkyl-5,5′-bithiazolidinylidene-2,4,2′,4′-tetrathiones (SS-R) are studied. The SS-R compounds have tilted stacking crystal structures, whereas the OS-R compounds show basically herringbone structures
