Indandione 1 was brominated to yield 2-bromoIndandione 2 which on further reacted with substituted thiocarbamides, carbamides, 2-aminothiophenols, 2-aminophenol and triazoles to furnished 3-substituted aniline-2-thia-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 3, 3-substituted aniline-2-oxa-4-aza-6,7-benzo-8-oxo-bicyclo [3.3.0]-1(5),3-octadiene 4, 2-Thia-5-aza-9-oxo-3,4-(3’-substitut...

H- and Cl-terminal groups of bicyclo[2.2.2]octane (BCO) derivatives in a mixed self-assembled monolayer (SAM) on Au(111) were imaged using a modified Si tip with a CaF(2) nanocluster to differentiate the two terminals, which have different electronegativities. In order to achieve this we fabricated a new sample holder, on which a CaF(2) single crystal and the mixed SAM on Au(111) could be mount...

(R)-1,2-Diaminobicyclo[2.2.2]octane was used as a starting material for the preparation, in solution or ball mill, of salen ligand. Five metal complexes were prepared high yield and their cytotoxic activities evaluated against Human Colon cancer HCT116 cell lines. The original manganese complex displayed highest activity with potency 16 fold higher than that cisplatin, demonstrating benefit bri...

Refiners add tetraethyl lead (TEL) and tetramethyl lead (TML) to gasoline to increase octane. In most situations, adding lead is the least expensive means of providing incremental octane to meet gasoline specifications. At sufficiently high levels, addition of lead can increase octane as much as 10 to 15 control octane numbers (Figure 1). Lead susceptibility (the gasoline’s propensity to increa...
