A number of ether- and thioether-substituted ferrocenes (1,1?-bis(1,3-dioxane-2-yl)ferrocene 1, 1,1?-bis(5-methyl-1,3- dioxane-2-yl)ferrocene 2, 1,1?-bis(4-methyl-1,3-dioxane-2-yl)ferrocene 3, 1,1?-bis[(R)-(-)-4-methyl-1,3-dioxane-2-yl]ferrocene 4, 1,1?-bis(4,6-dimethyl-1,3-dioxane-2-yl)ferrocene 5, and 1,1?-bis(1,3-dithiane-2-yl)ferrocene 6) were synthesised by direct condensation of 1,1?-diformylferrocene with the corresponding diols or dithiols. The crystal structures of 1, 5a, 5b, and 6 were determined by X-ray diffraction studies. Electrospray ionisation mass spectrometry was used to investigate the binding behaviour of 1 and 6 toward alkali as well as transition metal cations. The dioxane-containing species 1 showed high affinity toward Li+ and Na+, whereas the dithiane derivative 6 bound, as expected, preferentially to Hg2+. The Royal Society of Chemistry 2003.

A dimer bearing two phenylterthiophene parts linked by a chiral moiety with a minimized molecular volume has been synthesized. This chiral dimer exhibits a chiral nematic phase and its helical structure can be fixed by cooling rapidly. The helical pitch is shorter than the visible light wavelength and the reflection band can be tuned between near ultraviolet and infrared wavelengths by mixing enantiomers of the dimer or changing the temperature. The hole and electron mobilities in the chiral nematic phase are of the order of 10-5 cm2 V-1 s-1. Circularly polarized light emission has been observed in the chiral nematic phase. In the fluidic chiral nematic phase, circularly polarized photoluminescence can be switched to a non-polarized state reversibly by the application of the electric field.

However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4254-15-3

Resorcinol-dodecanal cyclotetramer 1 as an achiral host in chloroform forms hydrogen-bonded complexes with a variety of chiral di(poly)ols (2-24) including steroids and sugars. The complexation processes can be followed very conveniently by the induced circular dichroism (CD) spectroscopy. The binding constants as determined by CD titration increase in the order 15 (steroidal monool, K = 8.7 M-1) < 3, 6, and 8 (acyclic glycols, (4.9-7.1 × 10) < 9alpha, 10alpha, 12, and 13 (cyclic glycols and steroidal diols, (0.94-2.7) × 102 < 11 (steroidal triol, 6.9 × 102). This order reflects the extents of multiple host-guest hydrogen-bonding interactions. All of the resulting complexes exhibit CD with split Cotton effects as a result of exciton chirality induction in otherwise symmetric 1 upon binding of a chiral guest. The signs of split Cotton effects for complexes derived from glycols are correlated with the chiralities or absolute configurations of the guests, while those for sugar complexes are governed by the ring conformations (C1 or 1C) of sugar pyranoses. These results suggest that host 1 can be used as a novel, supramolecular probe for the assignments of stereochemistry of chiral guests.

Cobalt complexes of fluorous chiral salen ligands have been synthesized and tested as catalysts in the hydrolytic kinetic resolution of terminal epoxides. Whereas the activity of heavily fluorinated complexes was found to be rather low, a ‘light fluorous’ complex was shown to be an efficient and highly selective catalyst for this asymmetric ring-opening reaction. Several strategies for the isolation of reaction products and the recovery of the fluorous catalyst are also discussed.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about4254-15-3.Related Products of 4254-15-3

Marine-derived species, in particular, fungi, algae, sponges, and coelenterates are fertile grounds for the discovery of biologically and pharmacologically potent compounds. These molecules are structurally unique and possess a wide range of pharmacological activities. The rigid spiroacetal framework, that is, tetrahydro-spirofurofuranones is present in cephalosporolides E, F, H, and I, while the macrolactone structure is exemplified by cephalosporolides B, C, D, G, and J. These marine-derived molecular architectures are appealing to the synthetic community for their stereoselective synthesis. The present review represents a comprehensive overview of all the reported syntheses of these marine-derived molecules.
