Robust, soluble pentacene ethers.
We report the synthesis and characterization of a series of alkoxy-substituted silylethynylated pentacene derivatives (R = CH(2)CH(2), CHCH, CH(2)). All three compounds are easily prepared, soluble in common organic solvents, and stable both as solids and in solution. Two of the derivatives possess significant pi-face interactions in the crystal. Values for lambda(max) for these new pentacene d...
متن کاملGenotoxicity of glycol ethers.
The genetic toxicology of glycol ethers is reviewed. Ethylene glycol monomethyl ether (EGME) and diglyme have been more extensively studied than other members of this series. Most results indicate a lack of genotoxic potential, but certain tests have yielded positive responses with certain compounds. Ethylene glycol monoethyl ether (EGEE) induced sister chromatid exchanges and chromosomal aberr...
متن کاملEthers and Thioethers
Ethers are hydrocarbon derivatives containing a carbon-oxygen-carbon (C-O-C) fragment. Recall that carbon has a valence of four and thus requires four electrons or bonds to achieve an octet in its neutral state. Oxygen has a valence of six and thus requires two electrons or bonds to achieve an octet in its neutral state. In ethers there is a single oxygen atom bound to two carbons; in this bond...
متن کاملOrigin of Glycerol Ethers
Pieces of the digestive gland of the starfish, Asterias forbesi, were incubated in vitro with various radioactive lipid precursors in order to follow the biosynthesis of the alkyl and alkenyl glycerol ethers. Acetate-1-14C was incorporated readily into alkyl glycerol ethers of both neutral lipid and phospholipid fractions, but very poorly into the alkenyl glycerol ethers. Stearic acid-l-14C and...
