Crystal Structures of 4-Methyl-1-(3,4,4-trichloro-1-cyclohexylsulfanyl-2-nitro-buta-1,3-dienyl) Piperidine and 4-(3,4,4-Trichloro-1-decylsulfanyl-2-nitro-buta-1,3-dienyl) Morpholine and Spectroscopic Properties

The Vinylic SN Reactions of Nitrodienes with Heteroatom‐Substituted Nuchleophilies and Their Structural Studies

“…The noncoplanar structures of the butadiene fragment of these molecules and clear single bonds nature of the C2–C3 bonds [1.488(8) Å for 3a and 1.447(3) Å for 21a ] indicate the lack of delocalization of π‐electron density in the butadiene chain, which is apparently one of the major reasons for the inertness of polychlorobutadienes and their functional derivatives with nonplanar molecular structure relative to 1,4‐addition. The C–C bond lengths of the butadiene chain agree well with corresponding distances in the similar compounds . It is expected that mono(thio)‐ and N , S ‐substituted nitrobutadienes such as 3a and 21a yielded products such as a mixture of ( E )‐ and ( Z )‐isomers.…”

“…However, in the crystal structure of mono(thio)substituted nitrodienes reported in previous studies, it was noted that mono(thio)substituted nitrobutadienes were ( E )‐isomers and N , S ‐substituted nitrobutadienes were also ( E )‐isomers. As a consequence, it might be thought that the derived new S ‐ and N , S ‐substituted nitrodiene products were probably ( E )‐isomers . In this study, single crystal structures of compounds 3a and 21a showed that mono(thio)‐ and N , S ‐substituted‐3‐nitro‐butadiene compounds such as 3a and 21a were ( E )‐isomer.…”

Synthesis and Crystal Structures of 4,4-Dichloro-2-nitro-1,1,3-tris(phenylsulfanyl)-buta-1,3-diene and 4,4-Dichloro-2-nitro-1,1-bis(phenylsulfanyl)-3-(phenylsulfinyl)-buta-1,3-diene

“…According to a US patent, some thio-substituted dienes also exhibit high biological activity such as insecticide, herbicide and fungicide 2 .In recent years, certain mono-, di-, tris(thio) substituted compounds were obtained from the reactions of nitrodienes with thiols and dithiols [3][4][5][6][7][8][9] . There are some reports on the crystal structure of these compounds [10][11][12][13][14][15][16] . The oxidation reaction of organo sulphur compounds has been the focus of great interest recently in biochemistry and in industrial processes 17 .…”
