Benzene, thio

Thus, the rigid amide bonds and benzene rings in HubM3 are less costly to restrict conformationally than are the three-fold rotors in Flex(M)3 and benzene-thio(M)3. 

Trithiocyanuric acid 143 was reported to react with 1,3,5-trimercaptobenzene and a benzylic bromide melamine derivative to yield triazine-thio-M3 145 and benzene-thio-M3 146 (Scheme 20) <1996JOC1779>.

The reaction of 1,2,4,5-tetrafluorobenzene in NVV -dimethylimidazolidin-l-one (DMT) with sodium or alkaline methyl mercaptide gives l,2,4,5-tetrakis(methyl-thio)benzene [26] (equadon 16). 

An 5-(l-m-nitrophenyl-2-benzoyl)ethyl thioether was used to protect thio-phenols during electrophilic substitution reactions of the benzene ring. ... 

Fusion of an additional heterocyclic ring onto a benzodiazepine is well known to considerably increase potency. This increase in potency is apparently maintained when the benzene ring is replaced by thiophene. Thiophene aminoketone 161 is converted to the benzodiazepine analogue 164 via chloroacetamide 162 and then glycine derivative 163 by the same sequence as that used in the benzene series. Treatment of the product 164 with phosphorus pentasulfide gives the thio-amide 165 reaction of that intermediate with hydrazine leads to the amino amidine 166. Conden-... 

To 4.9 g of finely pulverized sodium in 50 ml of absolute benzene add dropwise with stirring 12 g of chlorobenzene in 50 ml of absolute benzene. As soon as the exothermic reaction begins, maintain the temperature by cooling between 30° and 35°C, and continue stirring for 2 to 3 hours. To the resulting phenyl sodium add dropwise 19.8 g of thio-xanthene in 120 ml of absolute benzene. The slightly exothermic reaction ceases after about 1 to 1 /j hours.

An interesting conversion was observed when 5-thiono-2,4,5,6-tetraphenyl-l,3,5-dioxaphosphorinane (23) was refluxed in benzene in an acidic medium (79IZV2136) with excess sulfur. 3-Thio-2,3,5-triphenyl-1,4,3-oxathiaphospholane (24) was formed. The following reaction mechanism may be proposed [Eq. (16)]. In favor of this mechanism is the fact... 

A further useful example is given by the trianion [Fe3S4(LS3)]3 LS3 = 1,3,5-tris[(4,6-dimethyl-3-mercaptophenyl)thio]-2,4,6-tris(/ -tolyl thio)benzene(3—). The molecular structure of its Fe3S4 core is illustrated in Figure 6.11...
