Reaction of 3,3’,4,4’-tetramethyl-1,1’-diphosphaferrocene 1 with an excess of benzoyl chloride
and AlCl3 afforded a ~1:1 mixture of meso- and rac-2,2’-dibenzoyl-3,3’,4,4’-tetramethyl-1,1’-
diphosphaferrocenes 2, which ...
Redox-Active Glycol Nucleic Acid (GNA) Components: Synthesis and Properties of the Ferrocenyl-GNA Nucleoside, Phosphoramidite, and Semicanonical Dinucleoside Phosphate

Ispinesib is a potent inhibitor of kinesin spindle protein (KSP), which has been identified as a promising target for antimitotic anticancer drugs. Herein, we report the synthesis of half-sandwich complexes of Ru, Os, Rh, ...
1JCH couplings in Group14/IVA tetramethyls from the gas-phase NMR and DFT structural study: a search for the best computational protocol
Nazarski, Ryszard Bolesław ; (The Royal Society of Chemistry, 2014-05-15)
; (The Royal Society of Chemistry, 2014-05-15)
Four tetramethyl compounds EMe4 (E = C, Si, Ge, and Pb) were studied by high-resolution NMR spectroscopy in gaseous and liquid states at 300 K. Extrapolation of experimental vapor-phase C-H J-couplings to a zero-pressure ...
How much do coulombic interactions stabilize a mesophase? Ion pair and non-ionic binary isosteric derivatives of monocarbaborates and carboranes
; ; ; Kaszyński, Piotr (Royal Society of Chemistry, 2014)
(Royal Society of Chemistry, 2014)
Replacement of the B− atom in the monocarbaborate anion, 1[10] or 1[12], and the N^+ atom in the pyridinium cation [Pyr] of a liquid crystalline ion pair with C atoms leads to an isoelectronic and isosteric non-ionic binary ...
Investigation of high Δε derivatives of the [closo-1- CB_9H_10] anion for liquid crystal display applications
; Kaszyński, Piotr ; ; (Royal Society of Chemistry, 2014)
; ; (Royal Society of Chemistry, 2014)
Two series of polar compounds 3[n] and 4[n] with longitudinal dipole moments ranging from 10 to 17 D were synthesized and investigated as additives to two nematic hosts, ClEster and CinnCN. Compounds 3[n] do not exhibit ...
Zwitterionic pyridinium derivatives of [closo-1-CB_9H_10]− and [closo-1-CB_11H_12]− as high Δε additives to a nematic host
; ; Kaszynski, Piotr (Royal Society of Chemistry, 2013)
(Royal Society of Chemistry, 2013)
Substituted closo-carbaborate–pyridinium zwitterions were prepared in 35–50% yield by reacting 1-amino-closo-1-carbaborates with 4-alkoxypyrylium triflates. Two of the new materials, 1[6]d and 2[10]b, exhibit a high ...
